In the design of the retaining and protecting structures of foundation excavation
the theory of Rankine’s earth pressure is used to calculate the earth pressure on the structure in the present code. The method of these design and calculation is built according to saturated soil mechanics. The results of these methods are not very satisfied. The equations of active earth pressure and passive earth pressure are deduced based on the theory of unsaturated soil mechanics. Finally
taking the actual project for example
the effect of suction and construction time on the earth pressure on the retaining and protecting structures of foundation excavation is studied according to the equations.
