岩溶隧道勘察阶段涌水量计算方法探讨

Discussion on Calculation of the Prediction of the Discharge Rate of Karst Tunnel Gushing in Investigation Stage

勘察阶段岩溶隧道涌水量的预测是隧道涌水量预测工作难点中的难点。从当今岩溶隧道涌水研究的现状出发,找出勘察阶段岩溶隧道涌水量预测存在的问题,并分析其原因,通过总结以往工程实例,得出一提高岩溶隧道在勘察阶段预测涌水量精度的方法,并辅以实例阐述。

The prediction of the discharge rate of karst tunnel gushing in investigation stage is the most difficult problem in the prediction of the discharge rate of tunnel gushing.The paper starts from the research state about karst tunnel gushing,in recent years,then,finds out some problems in the prediction of the discharge rate of karst tunnel gushing in investigation stage,and analyses their causations.Finally,summarizing some engineering examples,aquires a mathed for improving the pricision of the prediction of the discharge rate of karst tunnel ＋gushing in investigation stage.In order to explain it,the paper picks up an example specially.
