本文用数理统计方法建立了合肥地区一级阶地和河漫滩相的粘土与亚粘土的静探贯入阻力P_s同主要物性参数(例如液限W_L、孔隙比e,容重r,压缩模量E_s,地基承载力[R]等)之同的各种相关关系。并对这些关系进行了初步的讨论。可以看出,P与土的物性参数之间有着密切联系。因此,在合肥地区推广这种原位地基土测试方法,对于了解土的原位性质来说,是极其有效的。
In this paper, the static penetration resistance P_s of clay and subclay at the first terrace and floodplain in Hefei area is established by using mathematical statistics method. The main physical properties parameters (such as liquid limit W_L, porosity ratio e, bulk density r, compression modulus E_s, foundation Various correlations such as bearing capacity [R], etc.). And preliminary discussion of these relations. It can be seen that there is a close relationship between the physical parameters of P and soil. Therefore, the promotion of this method of in-situ soil testing in Hefei area is extremely effective for understanding the in-situ properties of soil.
