摘要
Abstract
In the construction of deep buried long tunnel in complex karst region, geological disasters such as water burst, wa-ter inrush, mud burst and so on are prone to occur and may lead to a series of groundwater environmental problems. Therefore, the tunnel should be constructed in non ( or weak) karst area to minimize the drainage of groundwater. Taking a deep buried long tunnel in complex karst area of water diversion project in central Yunnan Province as an example, we judged the development de-gree of the deep karst on macro scale and defined the accurate position of underground watershed in the study area based on hydrological and engineering geological survey and mapping, together with technical methods of drilling, groundwater tracer test and earth electromagnetic sounding. The results provided a reasonable, accurate and feasible basis for the optimization of tunnel route .关键词
