土体参数变化对斜抛撑支护基坑的影响研究

对于斜抛撑这种较为新颖的基坑结构支护体系，通过研究斜抛撑的平面应变模型，分析土体参数的变化对基坑围护结构与土体受力的变形与受力，得到了不同弹性模量、黏聚力以及内摩擦角的影响程度。不同的土体参数对应实际工程中不同的地质条件与环境，因此土体参数的分析可以研究斜抛撑这种新型围护结构的适用范围。

Study on Effect of Soil Parameter Change on Inclinded Bracing in Excavation

In respect of inclinded bracing, a new structural supporting system for foundation pit, the paper, by studying the plane strain model thereof, analyzed the deformation and stress of both the retaining structure and the soil mass when the soil parameters change, and found out the effect degree of different elastic modulus, cohesive force and internal friction angle. The different parameters of soil mass correspond to different actual geological conditions and environment, thus the analysis of soil parameters may be used to study the applicable scope of inclinded bracing.
