| Abstract: | Taking the diaphragm wall with joints on both sides used in irregular foundation pit as research object,and considering the spatial deformation factor,the expression of the potential energy of supporting system is established based on the reasonable simplified model.According to the minimum potential theory,the lateral deformation’s analytic calculation formula is derived.The effects of the main structural parameters on the maximum displacement are discussed.At last,it is verified from practical examples that the method is feasible. |
| Keywords: | diaphragm wall with joints on both sides spatial deformation principle of minimum potential ener-gy analytic calculation |
