摘要

动参数法包括频率法和频率-初速法已应用于检测各种地基和桩基的承载力。在用频率法检测地基承载力大小的基础上提出了一种改进的动参数法。首先

采用不同的压模面积

利用线性回归分析得到地基抗压刚度系数Cz和压模面积A的立方根的乘积值的大小

再计算了承压板面积为20m2时的地基抗压刚度系数

最后通过相关规范得到地基承载力的大小。并与静力法测试结果相比较

发现其结果非常相似。

Abstract

So far

the methods of dynamic parameters include method of frequency and method of frequency-muzzle velocity

which could apply to testing the bearing capacity of soil foundations and the pile foundations. Based on the method of frequency

a meliorative method of dynamic parameters is put forward. First

adopting different area of boards and using linear regression

the multiplying value of Cz （the rigidity coefficient of soil foundation） and A （the area of board）could be got. Then

the rigidity coefficient of soil foundation as the area of board of 20 m2 is got by computation. Finally

through correlative criterion

the value of bearing capacity could be got.
