| 摘 要： | 应用高密度电阻率法勘察宁淮高速公路南京老山隧道工程,查明了隧道YK5 280~ZK5 540段的地层分布和构造特征,并推断出鹰嘴山断层的位置和产状,结合勘察资料证明该断层为高角度逆断层。预测出隧道和断层破碎带相交处为浅部裂隙岩溶含水带中的优良导水带,该处涌水的可能性很大,其推断结果在施工中得到证实。说明高密度电法是进行隧道勘察和构造裂隙岩溶富水带探测的一种可靠手段。

| Abstract: | The principle of high density resistivity method is introduced.Using this geophysical method to geological investigation of Laoshan Tunnel project,the strata and geological structures are identified.Meanwhile,the position and attitude of Yingzuishan fault are determined.An aquiferous fracture zone is predicted and is proved later on.The engineering practice indicates that high density resistivity method is an effective geophysical method for tunnel engineering investigation and the aquiferous epi-karst zone exploration. |
