Application of geophysical exploration techniques in the survey of special long tunnels
Extra-long tunnel often passes through complex geological environment,which makes it hard to obtain compre-hensive geological information by applying traditional drilling method.However,it can better guide subsequent engineer-ing construction through applying geophysical exploration technology.The thesis introduces the basic principles of Con-trolled-source Audio-frequency Magnetotellurics(CSAMT)and utilization procedures of scalar measurement method.In-tegrating with specific engineering examples,it discusses its practical application process,and proves that can reduce po-tential tunnel construction risks and better guarantee the tunnel engineering safety as well by using the above-mentioned methods.
