| Abstract: | This paper briefly summarizes that earth pressure of wall back is distributed with wall＇s height; moreover, this earth pressure has non-linear relationship with the displacement. Due to the elevation of composite force point, the wall＇s stability mainly is controlled by anti-overturning. Combing with model experiment results, a calculation method for simulation on active earth pressure of rigid wall under non-limit state is presented. This calculation method could provide reference for the design and construction of retaining engineering. |
