目前,在我国沿海城市的地基基础设计中,基本上都遇到有软弱土层的问题。饱和软粘土的变形与承载能力也是我们设计首先要考虑的问题。太萨基(Terzaghi,K.)的固结理论正是我们最熟悉的理论依据。但是按照太萨基的固结理论计算出来的建筑物沉降规律,无论考虑了怎样的经验修正系数进行修正,与实测结果的比较中,有的在施工阶段、有的在长期的最终观测阶段,总有不太符合的情况出现。这就引发我

At present, in the foundation design of coastal cities in China, basically all have encountered the problem of soft soil. The deformation and bearing capacity of saturated soft clay are also the first issues to be considered in our design. The consolidation theory of Terzaghi, K. is exactly the most familiar theoretical basis for us. However, according to the theory of settlement of the settlement, the settlement rule of the building is calculated, no matter what kind of empirical correction coefficient is taken into consideration, compared with the measured results, some are in the construction stage and some are in the long-term final observation stage, There are always some inconsistencies in the situation. This triggered me
