【摘要】 通过对若干隧道的物探勘查表明,合理的运用高密度电法、地震折射波法和瞬态瑞雷波法以及声波测井法,可以有效的查明隧址区第四系覆盖层厚度、基岩垂向分带情况,推定断裂等构造破碎带的位置和产状,计算岩体波速、划分围岩级别,为隧址区的工程评价和隧址的合理选择提供科学依据。指出目前折射波法勘探存在的局限性,强调综合物探的合理性。提出采用高密度电阻率法、声波测井法和瞬态瑞雷波法的综合勘查方法进行隧道工程物探勘查,期望能为今后的隧道物探勘查提供指导。更多还原

【Abstract】 Through tunnel prospecting,it shows that appropriately using high-density resistivity method,seismic refraction method,Rayleigh wave method and acoustic velocity log method it can effectively identify the thickness of Quaternary covering level in the tunnel area and the vertical zone of rock mass,the location and occurrence of the fault and calculate the velocity of rock.This provides a scientific basis for engineering evaluation and rational choice of tunnel area.In this paper,it also points out the limitation of seismic refraction exploration.更多还原
