低应变法在微桩承载力检测中的应用

Application of Low Strain Method in Bearing Capacity Test of Micro Pile

微型桩是一种加固的结构,它具有良好的抗震的性能,目前微型桩在工程实践中广泛使用。本研究通过对低应变法的检测技术进行介绍,对微桩还有微桩的承载力进行研究。在此之后,对低应变法确定微桩的承载力进行分析研究,分析影响的因素和低应变法检测微桩承载力适用的添加,结果表明,在进行检测时,微桩的长度不能大于临界的有效长度;在检测的时候,要保证桩的完整性;在检测的时候需要有大量的、可靠性的动静对比资料。低应变法在微桩承载力检测中应用良好。

As a kind of strengthening structure,micro pile is widely used in engineering practice because of its good seismic performance. In this study,the testing technique of low strain method is introduced,and the bearing capacity of micro pile and micro pile are studied. After this,the low should determine the analysis on bearing capacity of micro pile method,and analyze the influencing factors of low strain detection for micro pile bearing capacity is added,the results show that the tested,micro pile length cannot be greater than the effective length of critical; at the time of the inspection,to ensure the integrity of piles need to compare data; there are a lot of movement and reliability at the time of detection. Low strain method is applied well in bearing capacity test of micro pile.
