摘要
物探测井技术属于原位测试方法的一种,通过将探头放入已成钻孔,利用地球物理方法测得地下岩层的物性参数,进而对设计、施工进行指导。通过南宁地铁勘察实例,介绍了物探测井技术在地铁勘察项目中的工作方法,提供了几种物性参数的理论及工程意义,并分析测井工作中仍存在的问题。
Geophysical well logging technology is a kind of in-situ test method, which can provide guidancefor design and construction by means of puttingprobe into the hole, using geophysical method to measure the physical parameters of underground rock stratum. Based on the investigation of Nanning subway, we introduced the geophysical well logging technology in metro survey project, provided the physical parameters of several theoretical and engineering significance, and analyzed the problems exist in the logging work.
