摘要
水利枢纽和水电工程绝大部分选址于地形陡峭、通行困难的深切河谷地段,地形条件较差,在这种地形条件下的地面物探勘察工作开展较难,成果精度较低;而充分利用地形及现有的平硐、钻孔等地质工程,采用地震波CT、电磁波CT进行勘察效果显著。通过工程应用说明,采用这些技术对节约勘察成本,提高勘探精度起到事半功倍的效果,勘察成果精度较高。
Most of water conservancy and hydropower projects are located in deep valley,and most of them are cliffy and have difficult transportation. It is difficult for ground geophysical surveying in this conditions. But seismic waves,electro-magnetic wave CT tomography survey can get good results by making full use of topographic conditions,exsiting tunnel,drilling and other geological engineering facilities. This technique helps to increase the precise of exploration,meanwhile it also reduces the cost of survey.
