静力触探试验(CPT)作为一种原位测试技术,可对测试土层的特性等作出比较全面的分析和评价.为探求杭州粉土和黏土静力触探参数与物理力学指标的相关性,分别采集杭州粉土和黏土两工程的静力触探参数及物理力学性质指标.根据相关方程、相关系数和相关统计图对粉土和黏土的静力触探指标进行比较,得到压缩模量和标准贯入度与粉土及黏土的静力触探参数呈正相关性,而且黏土相关性较粉土相关性好.其他的物理力学指标,如含水量、孔隙比、压缩系数,与粉土和黏土的静力触探参数均呈负相关性.
As a kind of in situ testing technology, CPT can make a comparatively comprehensive analysis and evaluation on the characteristics of soil test, etc. In order to find out the relationship between static claw parameters and physical and mechanical indexes of silt and clay in Hangzhou, , Respectively, static silting parameters and physical and mechanical properties of silt and clay in Hangzhou were collected.According to the correlation equation, correlation coefficient and related statistics, the static claw indexes of silt and clay were compared to obtain the compression modulus The amount and standard penetration are positively correlated with the static detective parameters of silt and clay, and the correlation between clay and silt is good.Other physical and mechanical indexes such as water content, void ratio, compressibility, Static shearing parameters of soil and clay are negatively correlated.
