摘要

研究目的: 地表失水问题在山岭隧道施工中日益突出，对该类风险进行识别与评估，并制定出合理的应对措施进行风险管理是十分必要的。

研究结论: 结合武广客运专线金沙洲隧道工程，通过全面分析影响地表失水风险的各个因素，建立了层次结构模型，利用 AHP 分析得出各因素的相对权重。通过对合成权重的排序，识别出对山岭隧道地表失水风险有重大影响的风险因素，找出各方面的薄弱环节，制定出合理有效的风险应对措施，降低地表失水风险等级，减轻隧道对周边环境水资源的影响和破坏，保证了工程的顺利进行，最终实现有效的风险管理。其理论、方法和思路可供同类工程借鉴。

Abstract

Research purposes: Water loss of the earth surface becomes more and more serious problem in construction of mountain tunnel． It＇s very necessary to recognize the risk of such problem and take the measures for control of such risk．

Research conclusions: Combined with construction of Jinshazhou Tunnel of Wuhan － Guangzhou Passenger Dedicated Line，by analyzing every fact that influences the risk of water loss，the hierarchy structure model was developed with AHP analysis method to get every factor＇s relative weight． Based on the sort of compound weight，the risk factors having significant impact on the water loss risk of the earth surface were distinguished，and the weak points in all aspect were found out． So the effective measures should be worked out to control and reduces the risk and the impact of the tunnel on environment for ensuring safe construction of tunnel and achieving the effective control of the risk． Such theory，method and thoughts on control of the risk could be as the reference to the similar works．
