隧道及地下工程岩溶危害预报的专家系统

EXPERT SYSTEM FOR PREDICTING KARST HAZARDS ENCOUNTERED IN THE CONSTRUCTION OF TUNNELS OR UNDERGROUND OPENINGS

在碳酸盐岩类地区修建铁路或公路隧道以及其它各种类型的地下工程时，可能遇到岩溶水突入、涌沙以及洞室坍塌等岩溶地质现象造成的危害，本文根据国内岩溶专家的经验制成专家系统，以便根据具体的水文地质和工程地质勘测资料，对工程所选定的位置和通过的地区的岩溶现象可能对工程发生的危害做出分级预报。

When a tunnel or any other type of underground opening is excavated in a carbonate rock area,lots of hazards due to the ekistence of karst such as the outburst of karst water,quick inflow of sand,opening collapese,etc. may possibly be met. This paper describes anexpert system developed on the basis of the experineces from Chinese experts in the field ofkarst sciences,￣ith the prediction of thin kind of hazards as its target. As a decision supportsystem, the prediction system can provide policymakers with the information about those hazards they have to consider in the processes of site determination,design and construction ofunderground projects so that they can avoid faults as far as possible,save investments and'complete the project punctually.This system has been primarily verified by experts. In addition to the applications in railwaytunnel construction,it can also be applied to hydraulic structures or underground mining forkarst hazard prediction.
