低应变检测基桩扩径现象

Low strain dynamic testing of piles on inspecting diameter - expanding piles

对于基桩扩径现象,从低应变反射波法检测原理入手,列出在不同位置不同程度的扩径所表现出的时域曲线,分析其易误判的主要原因,给出了正确评判扩径桩桩身完整性的方法。

From the principle of the low strain dynamic testing of piles inspecting the diameter - expanding pile, this paper lists the curves of piles that diameter expand in different position in vary degree. It analyzes the reasons that it is easy to wrong judgment and give the correct judgment to the pile integrity of diame- ter - expanding pile.
