在云南厂口隧洞工程施工中,根据不同地质问题,采用高密度电法、洞地间地震波CT和超前预报三种物探方法进行探测,探测结果均对地质灾害有较明确的反映,说明作为基本技术手段的物探方法在隧洞超前探测中能发挥重要作用。
In the Changkou tunnel project construction of Yunnan Province, three kinds of data respectively from high-density electric method, seismic wave CT between the hole and the ground and advanced forecast were used to carry out detection according to different geological problems. The results of the detection can reflect quite clearly various geohazards, suggesting that, as basic techniques, geo- physical methods can play important roles in the tunnel advanced detection.
