Passive earth pressure analysis of berm-retained excavation by upper bound method
Yantu gongcheng xuebao, 2020 The passive earth pressure should be known for the design of the berm-retained excavation, but no reasonable method for calculating the passive earth pressure has been found until now. According to the characteristics of the berm-retained excavation, the
