摘　　要：以梅州沿河工程中河滩相软土的土工实验数据为基础,利用kendall相关分析及多元回归分析法,综合分析该地区河滩相软土的指标分布情况及其工程特性,并以此为基础建立相应的抗剪指标的回归方程.结果表明:梅州地区河滩相软土具有高含水率、高孔隙率、高压缩性、低抗剪强度的工程特性.通过对各项指标进行kendall相关分析,量化物理力学指标相关程度并建立了相应的经验公式.研究成果可为有效减少勘察工作量,具有较好的实际应用价值.Based on the geotechnical experimental data of shoal facies soft soil in the Meizhou riverside project,using kendall correlation analysis and multiple regression analysis method,comprehensively analyze the index distribution and engineering characteristics of the shoal facies soft soil in the area,and build on this The regression equation of the corresponding shear resistance index.The results show that the shoal facies soft soil in Meizhou has the engineering characteristics of high water content,high porosity,high compressibility,and low shear strength.By performing kendall correlation analysis on each index,the relative degree of physical and mechanical indexes is quantified and the corresponding empirical formula is established.The research results can effectively reduce the survey workload and have good practical application value.
