摘要
根据上海某圆形基坑施工监测结果,对圆形深基坑受力特点进行了分析,认为圆形基坑以承受环向轴压为主,与主要承受经向弯矩的条形基坑有本质区别,提出圆形基坑受力分析应采用中厚壳理论,对上海该工程实例的分析表明,依据中厚壳理论计算得到的基坑位移与实测结果基本吻合.
Aiming at the construction of a cylindrical foundation pit located in Shanghai, the internal force of the cylindrical foundation pit is analyzed. It is presented that the diaphragm wall of cylindrical foundation pit is subjected mainly to the axial compressive stress in the circumference direction and it is different from the strip foundation pit which is subject to the bending moment in the radius direction. In the cylindrical foundation pit, the computing model should apply the theory of moderately thick shell.
