ANALYSIS ON ADDITIONAL FORCES OF SHAFT WITH DRAINAGE OF STRATUM
疏水沉降地层中井筒附加力理论分析

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.
