搅拌桩和砂桩复合地基质量的物探检测法

浆喷桩、粉喷桩、砂桩是目前软土地基处理常用的方法,对其质量检验,一般采用载荷试验、取芯等方法,但存在不能检验地基处理整体效果的缺点。通过物探检测砂桩、浆喷桩、粉喷桩复合地基的现场试验,探讨了该方法用于检验复合地基处理整体效果的适应性。两种物探检验方法均较适合检验复合地基的整体加固效果,是传统检验方法的一种有益补充。

Geophysical Detection of Quality Inspection for Cement-soil Deep Mixed Pile Composite Foundation and Sand Pile Composite Foundation

Deep cement mixed(DCM)pile,jet mixing pile,and sand pile were commonly used for soft ground improvement,in which their quality was tested by loading test or core drilling method,but there are several shortcomings in these methods,for example,test results couldn’t reflect the integrity of composite foundation.By in situ test of geophysical detection for composite foundation of sand pile,DCM and jet mixing pile,its compatibility was discussed.Test results showed that the integrity of composite foundation could be tested by these two geophysical detections.
