由于深层搅拌桩成桩工艺的特殊性,其施工质量及处理效果受到人们的普遍关注。规范规定的质量检测方法有开挖检查、钻孔取芯、标准贯入及静载试验等,但上述方法投入大,效率低,特别的桩身完整性检验针对性较差。近几年,在桩基检测实践中,采用低应变反射波对深层搅拌桩进行桩身完整性检测,取得了较好的效果。 Due to the peculiarity of deep mixing pile forming technology, its construction quality and treatment effect have been widely concerned by people. The quality inspection methods specified in the code include excavation inspection, core drilling, standard penetration and static load test, etc. However, the above methods are expensive and inefficient, and the pile integrity inspection is poorly targeted. In recent years, in the pile foundation testing practice, the low strain reflected wave is used to test the pile integrity of the deep mixing pile, and good results have been obtained.
