土阻力对低应变动测影响的计算机仿真分析

Influence of Soil Resistance on Low Strain Reflected Wave Forms of a Pile in Its Dynamic Test

以一维波动理论为基础 ,利用计算机仿真程序 ,对运用低应变反射波法检测桩身完整性的过程中 ,土层的分层状况对检测波形的影响进行了讨论。结果表明 ,不同的土层状况对波形有不同的影响 ,而且具有一定的规律性。

Based on one dimensional wave theory,the influence of soil resistance on the low strain reflected wave forms of a pile in its dynamic integrity test is discussed by using a simulation software.Results show that different kinds of storied soil have different influence on the wave forms.So it is necessary to consider the condition of the soil around a pile in its dynamic integrity tset to avoid mistakes in a diagnosis.
