本文介绍了以地下连续墙作为承重结构的墙一桩一箱复合基础的共同作用问题,推导了墙一桩一土位移影响系数,应用桩土共同作用理论及Mindlin公式,深入计算分析了墙一桩一土体系的共同作用,进而得出了墙一桩一箱复合基础共同作用的计算公式。通过对新闸路地铁车站结构的计算与分析,得出了此类复合基础的沉降、内力以及荷载分担比例等规律性的结论,可供工程界参考利用。 This paper introduces the joint action of a composite wall with a continuous diaphragm wall as the bearing structure, deduces the coefficient of displacement of a wall and a soil, applies the pile-soil interaction theory and Mindlin’s formula, and analyzes and analyzes the wall in depth. The joint action of the pile-soil system led to the calculation formula for the joint action of a wall-pile composite foundation. Based on the calculation and analysis of the Xinzha Road subway station structure, the conclusions of such composite foundation settlement, internal forces, and the proportion of load sharing and other regularities are obtained, which can be used by the engineering community for reference.
