摘要

为了解决隧道沿线孤石影响盾构的顺利掘进，采用物探方法探测隧道沿线孤石的赋存情况，介绍了孤石区域的地球物理特征，对孤石探测的物探方法从重、电、震、测井、综合物探等方面进行了分类和介绍，有以往使用的老方法，也介绍了孤石探测的新方法，为今后不同环境条件下孤石物探探测方法的选择提供了一定的指导作用，另外，采用综合物探方法对两种或多种方法进行对比，可提高物探解译精度。

Abstract

Boulders on tunnel alignment is adverse for shield tunneling and geophysical prospecting is commonly used in boulders detecting along shield tunneling alignment.In this paper,the geophysical characteristics of boulder area are introduced and the geophysical prospecting methods for boulder are classified and presented,including gravity prospecting,electrical prospecting,seismic prospecting,well logging and compositive geophysical prospecting.In addition,the comparison of two prospecting methods or several prospecting methods by compositive geophysical prospecting can improve the precision of geophysical prospecting.Thus this paper can provide references for boulder detecting in various conditions by geophysical prospecting.

Key words： boulder; geophysical characteristic; gravity prospecting; electrical prospecting; seismic prospecting; compositive geophysical prospecting
