摘要
文中基于理论分析,结合现场试验,对静力触探状态参数方法求解公式进行优化,得出孔压静力触探与最大剪切模量的关系,以此研究经验公式预测的准确精度。结果表明,随着土层深度的增加,孔隙水压力逐渐加大,土层深度与剪切波速成正比,可以反映土体特质;状态参数可反映土体结构类别,其对应公式可以增加对软土最大剪切模量预测的精度,反映土体动力特性;有状态参数的经验公式拟合程度更高,准确性更强,预测性更加精准,对孔压静力触探的软土最大剪切模量研究更加全面。
Based on theoretical analysis and combined with field tests,the solution formula of static touch state parameter method is optimized to obtain the relationship between pore static touch and the maximum shear modulus,so as to study the accurate accuracy of empirical formula prediction.The results show that with the increase of soil depth,the pore water pressure gradually increases,and the depth of soil layer is proportional to the shear wave,which can reflect the characteristics of the unearthed body,and the corresponding formula can increase the accuracy of the maximum shear modulus of soft soil,and the empirical formula of state parameters is better and more accurate,and the research of the maximum shear modulus of hole pressure is more comprehensive.
