Sample solution

Dante Alighieri played a critical role in the literature world through his poem Divine Comedy that was written in the 14th century. The poem contains Inferno, Purgatorio, and Paradiso. The Inferno is a description of the nine circles of torment that are found on the earth. It depicts the realms of the people that have gone against the spiritual values and who, instead, have chosen bestial appetite, violence, or fraud and malice. The nine circles of hell are limbo, lust, gluttony, greed and wrath. Others are heresy, violence, fraud, and treachery. The purpose of this paper is to examine the Dante’s Inferno in the perspective of its portrayal of God’s image and the justification of hell. 

In this epic poem, God is portrayed as a super being guilty of multiple weaknesses including being egotistic, unjust, and hypocritical. Dante, in this poem, depicts God as being more human than divine by challenging God’s omnipotence. Additionally, the manner in which Dante describes Hell is in full contradiction to the morals of God as written in the Bible. When god arranges Hell to flatter Himself, He commits egotism, a sin that is common among human beings (Cheney, 2016). The weakness is depicted in Limbo and on the Gate of Hell where, for instance, God sends those who do not worship Him to Hell. This implies that failure to worship Him is a sin.

God is also depicted as lacking justice in His actions thus removing the godly image. The injustice is portrayed by the manner in which the sodomites and opportunists are treated. The opportunists are subjected to banner chasing in their lives after death followed by being stung by insects and maggots. They are known to having done neither good nor bad during their lifetimes and, therefore, justice could have demanded that they be granted a neutral punishment having lived a neutral life. The sodomites are also punished unfairly by God when Brunetto Lattini is condemned to hell despite being a good leader (Babor, T. F., McGovern, T., & Robaina, K. (2017). While he commited sodomy, God chooses to ignore all the other good deeds that Brunetto did.

Finally, God is also portrayed as being hypocritical in His actions, a sin that further diminishes His godliness and makes Him more human. A case in point is when God condemns the sin of egotism and goes ahead to commit it repeatedly. Proverbs 29:23 states that “arrogance will bring your downfall, but if you are humble, you will be respected.” When Slattery condemns Dante’s human state as being weak, doubtful, and limited, he is proving God’s hypocrisy because He is also human (Verdicchio, 2015). The actions of God in Hell as portrayed by Dante are inconsistent with the Biblical literature. Both Dante and God are prone to making mistakes, something common among human beings thus making God more human.

To wrap it up, Dante portrays God is more human since He commits the same sins that humans commit: egotism, hypocrisy, and injustice. Hell is justified as being a destination for victims of the mistakes committed by God. The Hell is presented as being a totally different place as compared to what is written about it in the Bible. As a result, reading through the text gives an image of God who is prone to the very mistakes common to humans thus ripping Him off His lofty status of divine and, instead, making Him a mere human. Whether or not Dante did it intentionally is subject to debate but one thing is clear in the poem: the misconstrued notion of God is revealed to future generations.

Lateral Earth Pressure and the Importance of Retaining Walls

Lateral earth pressure, the force exerted by soil on a retaining structure, is a critical factor in geotechnical engineering. It plays a crucial role in the design and stability of retaining walls, structures designed to hold back soil masses and prevent slope failures. Understanding lateral earth pressure is crucial for ensuring the safety and longevity of these structures.

Conceptual and Technical Issues

Types of Lateral Earth Pressure:

  • At-Rest Pressure (K0): This is the pressure exerted by soil when it is undisturbed. It is generally lower than active and passive pressure.

  • Active Pressure (Ka): The pressure exerted by soil when it is moving away from the retaining wall. This is the minimum pressure a retaining wall needs to withstand.

  • Passive Pressure (Kp): The pressure exerted by soil when it is pushed towards the retaining wall. This is the maximum resistance a retaining wall can provide.

Conceptual and Technical Issues

Types of Lateral Earth Pressure:

  • At-Rest Pressure (K0): This is the pressure exerted by soil when it is undisturbed. It is generally lower than active and passive pressure.

  • Active Pressure (Ka): The pressure exerted by soil when it is moving away from the retaining wall. This is the minimum pressure a retaining wall needs to withstand.

  • Passive Pressure (Kp): The pressure exerted by soil when it is pushed towards the retaining wall. This is the maximum resistance a retaining wall can provide.

Factors Influencing Lateral Earth Pressure:

  • Soil Properties: The type of soil, its density, and its angle of internal friction significantly impact lateral pressure. Cohesive soils exert higher pressure than granular soils.
  • Wall Movement: The movement of the retaining wall, whether towards or away from the soil, significantly affects the pressure exerted.
  • Water Table: The presence of groundwater influences lateral pressure, as water increases the effective weight of the soil.
  • Surcharge: Additional loads applied to the soil surface, like buildings or traffic, increase lateral pressure.

Design Methods

Several methods are used to estimate lateral earth pressure:

  • Rankine’s Theory: This theory provides a simplified approach to calculate active and passive pressure for a rigid wall with no movement. It assumes a homogenous soil with a specific angle of internal friction.
  • Coulomb’s Theory: This theory considers wall movement and soil properties more comprehensively, offering a more accurate estimation for complex scenarios.
  • Logarithmic Spiral Method: This method accounts for the non-linear distribution of stress in the soil mass and provides more accurate results for certain situations.

Importance of Retaining Walls

Retaining walls are essential in various civil engineering applications, ensuring stability and safety in diverse situations:

  • Highway and Railway Construction: They support road embankments and prevent soil erosion along slopes, ensuring safe and stable infrastructure.
  • Building Construction: They support basements and provide stability to structures built on sloped terrain, mitigating potential landslides.
  • Land Reclamation: They facilitate land reclamation projects by holding back water and soil, creating new land areas.
  • Erosion Control: They help prevent erosion by holding back soil and stabilizing slopes.

Examples

  • Highway Embankment: A retaining wall supports the embankment of a highway, preventing soil slippage and ensuring the stability of the roadway.
  • Basement Wall: A retaining wall provides stability to a building’s basement, preventing the soil from exerting excessive pressure on the foundation.
  • Landslide Prevention: A retaining wall is used to stabilize a slope prone to landslides, mitigating potential hazards and ensuring public safety.

Conclusion

Lateral earth pressure is a crucial factor in the design and stability of retaining walls. Understanding the concepts, influencing factors, and design methods related to lateral earth pressure is critical for ensuring the safety and longevity of these structures. Retaining walls play a crucial role in various civil engineering projects, ensuring stability, safety, and successful construction in challenging terrain.
