摘　　要：根据桩基理论 ,采用广义剪切位移法 ,考虑时间、土性及井深等因素 ,求解出疏水沉降地层中井筒附加力的理论解 ,得到疏水地层井筒附加力的大小和分布规律 。According to the theory of pile foundation, considering the drainage time of the stratum, soil properties, and the depth, the theoretical value of the additional forces can be obtained for the shaft by using generalized shearing displacement. The variation rule of the additional forces can be also obtained. The research results can provide a theoretical basis for design practice.
