多种因素对桩基低应变反射信号的影响分析

Influencing Factors on the Low Strain Reflective Signals in Pile Integrity Tests

探讨了低应变反射波法在具有波阻抗介质中的传播,通过分析低应变反射信号的多种影响因素、反射特性等,进行信号分析和波形的判别,以达到准确判读的目的。通过工程实例,在考虑多种影响因素的前提下,对波形进行分析,用定性解释和定量化计算的方法进行缺陷的准确判别,并根据取芯资料进行验证。

This paper focuses on the dissemination problem of the low strain reflection in the wave impedance medium.Throughout analyzing the influencing factors and echoing characters of the low strain reflection signals,etc.,the analysis of more clear and distinctive signals can be achieved.The interpretation of the signal can be verified by the coring results.
