Limited soil body soil pressure acquisition method considering soil separation width in adjacent underground project
The invention discloses a limited soil mass soil pressure acquisition method considering the soil separation width in an adjacent underground project. The method comprises the following steps of determining foundation pit design parameters, load parameters and physical and mechanical parameters of a rock-soil mass; determining an initial slip crack surface inclination angle; acquiring the gravity acting power, the ground load acting power, the dissipated energy loss acting power and the pressure acting power of the soil body; establishing a relational expression of energy consumption balance, and obtaining a soil pressure resultant force value and a critical failure angle; and obtaining a critical depth, and obtaining a soil pressure distribution condition along the depth. According to the limited soil mass soil pressure acquisition method considering the soil separation width in the adjacent underground project, the excavation safety of foundation pits on the two sides of the soil separation in the adjacent underground project can be evaluated and predicted in advance, and a basis is provided for design of an inner support.
一种考虑邻接地下工程中隔土宽度的有限土体土压力获取方法，包括以下步骤：确定基坑设计参数、荷载参数、岩土体的物理力学参数；确定初始的滑裂面倾角；获取土体的重力做功功率、地面载荷做功功率、耗散能损失做功功率以及压力做功功率；建立能耗平衡的关系式，获取土压力合力值和临界破坏角；获取临界深度，得到沿深度的土压力分布情况。本发明的考虑邻接地下工程中隔土宽度的有限土体土压力获取方法，有利于提前对邻接地下工程中隔土两侧基坑开挖安全性的评价和预测，并对内支撑的设计提供依据。
