摘要

摘要: 通过室内试验,分析了上海地区重塑土抗剪强度参数与土体塑性指数的关系,及各土层抗剪强度与土层深度的关系。研究结果表明,重塑土的抗剪强度与土的塑性指数间线性相关性不大,且随着土层深度增加,内摩擦角逐渐减小。

Abstract: n this paper, based on the laboratory test, analyzed the relationship between the shear strength and plastic index of remolded clay in Shanghai. And also analyzed the relationship between the shear strength and the depth of soil layer .The results indicate that the shear strength and plastic index of the remolded clay has little linear correlation. And with the depth of soil increasing, the angle of internal friction decreases gradually.
