The selection of geological prospecting in different stages(initial-prospecting, detailed-prospecting)(2)the selection of geological prospecting in the deep-laid and shallow-laid of tunnel project (3)the selection of geological prospecting of tunnel projecting in different geological conditions Finally, the author summed up main problems needing to be solved in tunnel engineering geological prospecting as follow:(1)differentiate stratum and find out the depth and thickness of different stratums in the tunnel section (2)find out geological structure and existence situation of fault, broken zone and weak plane (3)find out weathering level of bed rock to classify surrounding rock combining speed materials (4)differentiate stratum structure of the entrance of tunnel to judge the stability of it (5)find out existence situation and performance of ground water (6)situations of other harmful geological phenomenon In view of above problems and classification of surrounding rock, the author showed principles of rational choosing of methods in geological prospecting and counted disperse range of physical character parameter value in different petrosal character, getting achievements as follow:(1)summarization of effect, merits and demerits of different geological prospecting methods in the tunnel geological investigation (2)method selection and arrangement principle of tunnel engineering geological prospecting in different geological conditions and prospecting stages (3)According to previous experience and cases, the author concluded the物性parameters most in use ,and showed the basis of selecting geological prospecting methods in different geological conditions.

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。
