摘要
通过利用高密度电法对兰渝铁路某施工隧道涌水通道的勘查工作,查明了掌子面前方500m内的围岩含水情况,确定储水层及岩性接触带等可能的地下水涌水通道,为隧道制定合理防排水措施提供了依据。面对涌水隧道的勘查,高密度电法具有成本低、效率高、勘查距离长、效果明显等优点,不失为一种值得大力推广的好方法。
Through surveying water gushing on a tunnel of the Lanzhou-Chongqing Railway with the high-density resistivity method,the surrounding rock aquifer in front of working face within 500meters is detected,the groundwater aquifer and lithology contact zone or gushing water channel are determined,which has provided a basis for taking a reasonable measure for waterproofing and draining.Facing tunnel of water gushing surveying,high-density resistivity method has the characteristics of low cost,high efficiency,longdistance survey and good effect.The method is worth spreading.
