高家坪隧道岩溶水系统识别及涌水量预测
Karst Water System Identification and Water Inflow Prediction in Gaoj iaping Tunnel
摘要
Abstract
To find out the recharge source of the water inrush point at the ZK45 + 995 m of Gaojiaping tun-nel in YiBao highway under construction and the hydrogeological conditions of the tunnel area and to pre-dict water inflow based on the investigation and analysis of karst development law in the tunnel area,this paper carries out twice groundwater tracer tests.The results indicate that ZK45 + 995 m water inrush point under the supply comes from Xiashang karst depression on the northern side of the tunnel with the catchment area of 0.66 km2 .The karst pipe at the water inrush point,the west branch of Huanglongdong karst water system,is the single karst pipe type,where the maximum velocity of the groundwater is 341 m/d with the average flow velocity of 244 m/d.As the groundwater flow rate is fast,the pipeline medium is well-developed.According to the tracer test of karst water system which divides the boundary between Gandongping and Huanglongdong karst water system,and based on the long-term precipitation and spring discharge monitoring data of Huanglongdong Spring and the method of rainfall infiltration,the paper pre-dicts that the potential maximum and normal water inflow at ZK45+995 m water inrush point of the Gao-jiaping tunnel in the future will be 13 216 m3/d and 5 940 m3/d.The paper provides the hydrogeological ba-sis for the establishment of water prevention and control of tunnels.关键词
