论文中用几个应用实例来说明：(1)不同勘察阶段物探工作的选用；(2)深埋、浅埋隧道工程物探工作的选用；(3)不同地质条件隧道工程物探工作的选用。最后总结归纳出隧道工程物探所需要解决的问题主要有：(1)划分地层，查明隧道通过剖面的各地层深度与厚度。(2)查明地质构造，隧道轴线段有无断层、破碎带、软弱层面等。(3)查明基岩风化程度，从而结合速度资料进行围岩分级。(4)划分洞口地层结构，判断洞口稳定性。(5)查明地下水赋存情况及其活动动态。(6)其他不良地质现象存在情况。针对上述需要查明的地质问题与计算围岩分级情况，论文提出合理选用物探方法的原则，并统计了物性参数值在不同岩性中的分布范围。得出以下研究成果：(1)总结出各物探方法在隧道地质调查中的作用和优缺点。(2)得出不同地质条件下和不同勘察阶段，隧道工程物探方法选择和布置的原则。(3)根据以往工作经验和事例，对常用的物性参数进行了归纳总结，同时介绍了不同地质条件下物探方法选择的依据。
