Diaphragm (slurry) wall example

Diaphragm (slurry) wall example with DeepEX


A slurry wall excavation example will be analyzed with DeepEX. The following data is available:

a) Soil properties: Sand, friction angle = 30 degrees, total unit weight 120 pcf, loading modulus of elasticity Eload= 300 ksf, reloading modulus of elasticity Eur = 900 ksf. Ultimate bond resistance for ground anchors 40 psi.


b) Excavation depth: 25 ft, cantilever stage 10ft, ground anchor at 8ft depth at 15 degrees. Reinforced piles spaced at 6ft off center, while pile diameter is 2.5ft. Include 600 psf traffic surcharge 1ft behind the wall for a length of 20ft.


Objective: Design the slurry wall and the ground achors with allowable stress methodology and obtain a wall embedment safety factor of 1.5. Use reinforced concrete and steel rebars.

By double-clicking on the wall, we can define the wall section parameters through a user-friendly dialog. We simply have to select the wall type, choose diaphragm wall thickness and define the longitudinal and shear reinforcement.

Supports and loads can be added graphically on the model area, by using the Draw Loads and Draw Supports options in the General tab of DeepEX. After we draw the load or the support on the model, the Edit Options dialogs appear. There, we can define the load magnitude, the load position, the support position and structural section etc.

In the Design tab of DeepEX, we can select to assign US allowable settings on this model for the structural design. This option will assign ACI for concrete and ASD code for steel design.

After the analysis is completed, the Analysis and Checking summary appears. There, we can review the maximum deflection, moment and shear values and the wall and support structural and geotechnical checks.
