摘　　要：本文通过反演分析法,对已建立的土层剪切波速测试值与标准贯入击数的相关关系式,采用剪切波速测试参数法,对十项工程估算了桩基总沉降量,并与实际沉降量作了对比。建立的计算方法合理、简单,计算参数能正确反映地基土的力学性质,适用于各种桩基土类型。The paper presents an inversive analysis method to evaluate the total settlement of pile foundation using the shear velocity parameter, which is derived by the correlation formula of standard penetration test and s-wave velocity already established. The result is satisfactory after the contrast of calculation and the in-situ settlement surveying in 10 projects. The method is simple and reasonable in that the parameter can correspond the mechanic properties of the foundation soil correctly, also is suitable for varieties of type of pile foundation.
