Earth pressure on supporting structures of asymmetric excavations considering their displacement

The reason of earth pressure alteration is analyzed, and the formula for calculating the earth pressure considering the displacement of structures of asymmetric excavations are put forward. The earth pressure is calculated, compared and analyzed according to the monitoring data. They are almost equal. At the same time, the earth pressure of asymmetric excavations is the comprehensive result of soil displacement around them. The soil displacement is almost equal to the deformation of structure and earth pressure is less than the internal force of supporting structures. A formula for earth pressure considering water pressure and asymmetric displacement is concluded. It is concluded that the earth pressure for dewatering gets less and it benefits to the stability of excavations, and vice versa during raining. The earth pressure is nearly equal to the force of lining. It may be useful for the design of similar projects.
