内支撑基坑群开挖相互影响的三维数值分析OA北大核心CSTPCD
3D Numerical Analysis on the Interaction of Group Foundation Pits Supporting with Strut
通过 Z-Soil 岩土三维分析软件,以小应变硬化土(hardening soil model with small strain stiffness, HSS)模型为基础,建立地连墙与内支撑联合支护的群体基坑开挖的三维数值模型。对基坑土体的的竖向位移以及地连墙的变形和受力进行了分析,讨论了基坑间距的影响。分析结果表明:临坑的开挖使紧邻的坑间土堤沉降增加约1倍,使群坑周边沉降增加约10%;先开挖的基坑支护结构受力、变形增大,后续开挖的基坑的地连墙…查看全部>>
The three-dimensional numerical model of lined up group foundation pits supported by diaphragm wall and in-ternal strut system were built with Z-Soil geotechnical FEM software based on the hardening soil model with small strain stiffness (HSS)model.The vertical displacement of soil,deformation and stress of the diaphragm wall were analyzed. The impact of pit spacing was also discussed.The analysis results show that because of the excavation of nearby pits,th…查看全部>>
