浅层土体的静力载荷试验曲线与土体力学参数的关系

The research is carried out on the relationship between the subsurface soil mechanical properties and the in-situ static loading test curves with the help of in-situ dynamic penetration test on the subsurface soil, the static loading test and the numerical simulation; The influence of stress application's way on the soil mechanical character and the impact of stress paths on the soil resistance ant deeply studied. Based on these analyses, some simple in-situ testing methods on subsurface soil have been developed and these methods have been found different applications in various engineering construction practice.
