静力触探工作原理及在上海软土地区工程勘察中的应用

Working Principle of Cone Penetration Test and Its Application in Engineering Investigation of Soft Soil Area in Shanghai

摘要:

概述了当前国内外静力触探测试技术的发展历程，探讨了静力触探的工作原理及其划分情况；通过土层划分、土类定名、确定单桩极限承载力及地基承载力、进行地基土液化情况判别以及测试地基土物理力学参数指标等，分析了上海软土地区采用静力触探测试技术在勘察中的应用依据。

Abstract:

The development course of cone penetration test (CPT) technology at home and abroad is summarized. The working principle and division of CPT are discussed, including the division of soil layer and the naming of soil type. The ultimate bearing capacity of single pile and bearing capacity of foundation are determined. The liquefaction of foundation soil is distinguished. And the physical and mechanical parameters of foundation soil are tested. The application of CPT used in the soft soil area in Shanghai is analyzed.
