为解决水土压力合算和分算的争议，从理论上证明粘性土水土合算在某些情况下的合理性，基于微观层面分析了土中孔隙及土中水的类型及特征，研究了水土共同作用的微观机理，建立了临界重度方程及估算公式，给出了粘性土传递孔隙水压力的判别公式；选取不同地区粘性土，进行重力失水试验，试验结果表明：试验值与公式计算值差异很小，试验验证了公式的合理性。综合机理分析及试验成果，证实了对于现有基坑工程中所涉及的粘性土，其孔隙中仍然存在可流动的孔隙水，一般都能传递孔隙水压力，水土压力应当区别对待。

In order to resolve controversy of separate and combined calculation of water and earth pressures and to theoretically prove that combined calculation of water and earth pressure of clay is reasonable under some circumstances. The formation character of pores in the clay,the existence mode of pore water, the analysis of micro-mechanism of interaction of water and clay is established. The equation and estimating formula of critical density is defined to discriminate whether compact clay can transfer pore water pressure;The gravity dehydration test was studied by selecting different local clay, and the test result shows the slight differences between the results of test and estimated value, and the test verification of the formula rationality.The conclusion that clay is related to existing foundation pit project can generally transfer pore water pressure based on the studies above.
