Backfill sand supported by a concrete retaining wall (Lateral Earth Pressure) Abaqus
This example been chosen from Example 7.3 Sam Helwany book
In this example we intend to simulate backfill sand supported by a concrete retaining wall in the Abaqus software. also we intend to calculate the Lateral Earth Pressure exerted on the retaining wall
The sand layer is 3 m high. A 3-m-high retaining wall provides lateral support to the soil
The concrete retaining wall is assumed to be linear elastic with a Young’s modulus of 21.3 GPa and a Poisson ratio of 0.2
The sand layer is assumed to be elastoplastic, obeying the cap model with cap hardening properties
In this example , we use two steps , in the first step , we apply a 7 kPa surcharge pressure at the surface of the backfill also we apply weight of the backfill soil and retaining wall in this step
There are three possible types of lateral earth pressure that can be exerted on a retaining wall. 1- At-rest earth pressure 2- Active earth pressure 3- Passive earth pressure
At rest earth pressure
At-rest earth pressure occurs when the retaining wall is not allowed to move away or toward the retained soil
In this example we calculate the at-rest lateral earth pressure exerted on the retaining wall using abaqus
Active earth pressure
Active earth pressure occurs when the retaining wall is permitted to move away from the retained soil
In this example we calculate the active lateral earth pressure exerted on the retaining wall using abaqus
Passive earth pressure
Passive earth pressure occurs when the retaining wall is forced to move toward the retained soil
In this example we calculate the passive lateral earth pressure exerted on the retaining wall using abaqus
