CORRELATION ANALYSIS OF PHYSICAL AND MECHANICAL CHARACTERISTICS INDEXES OF SOFT SOIL FOR THE LAKESHORE NEW DISTRACT IN HEFEI
-
摘要: 基于合肥滨湖新区百余组软土的土工试验成果，对该地区软土的物理力学指标进行统计，并利用MATLAB软件对各物理力学参数之间进行相关分析，得到了各指标间的相关关系式。结果表明：合肥滨湖新区软土具有高含水率、高孔隙比、高压缩性及低抗剪强度等典型的软土特征；孔隙比与天然含水量、压缩系数与天然含水量、重力密度与天然含水量、压缩系数与孔隙比具有很好的线性关系，而含水量与黏聚力、内摩擦角之间具有非线性关系。Abstract: Based on the geotechnical experiment results of over 100 samples for soft soil of the lakeshore new distract in Hefei, the correlation equations between each index were obtained by regression analysis of the correlation analysis of all kinds of the physical and mechanical parameters using MATLAB.The results showed that the lakeshore new distract soft clay had typical features like high water content, large void ratio, high compressibility and low shear strength.There was an excellent linear relation between void ratio and natural water content, and compressibility and natural water content, bulk density and natural water content, and compressibility and void ratio;there was non-linear relation between natural water content and cohesion, and natural water content and internal friction angle.
