摘要
列举了应用反射波法对混凝土夯式扩底灌注桩几种缺陷的典型测试曲线,通过缺陷桩的开挖,验证了测试结果,分析了产生缺陷的原因。
This paper enumerates several typical test curves of defects in cement rammed-bottom-enlarged compaction pile with reflected wave method. Inspection result was verified by excavating the defective piles, and the causes of such defects were analyzed.
