摘要
基于广州市多个工程项目的岩土工程勘察资料,通过一元回归分析,揭示了各物理指标之间及压缩系数与物理指标之间的相关关系,建立各物理力学指标之间的回归方程;并通过多元回归分析,建立内摩擦角与含水量、孔隙比及黏聚力与含水量、塑性指数之间的回归方程,有助于估算该地区软土的力学特征,研究的结果为该地区软土工程的取值提供了一定的依据。
The paper is based on all kinds of data of geotechnical engineering projects in Guangzhou city.Through unary regression analysis,the correlation in the various physical parameters and the relationship between the compression factor and physical parameters are revealed. And the regression equation in the physical and mechanical indicators is established. With the multiple regression analysis,the regression equation of the internal friction angle,water content and void ratio and the regression equation of cohesion,water content and plasticity index are revealed.This study helps estimate the mechanical characteristics of soft soil.The research results provide a certain basis for the value of soft soil engineering in this area.
