摘　　要：为研究古风化壳隔水性能、了解其阻水作用,建立了古风化壳隔水性能评价指标体系,以底板突水评价方法—脆弱性指数法为对照,采用基于GIS的层次分析法,复合叠加生成各自安全评价分区图,经对比分析得出古风化壳隔水性能评价分区与突水脆弱性评价分区较为相似,对底板突水评价的安全分区影响作用明显,具有较为良好的隔水性。In order to study the weathering crust waterproof performance,to understand its water blocking effect. Through establishing the evaluation index system of ancient weathered crust water-barrier performance,and taking the evaluation method of water inrush of the floor-vulnerability index method as the control, the comparative analysis shows that the ancient weathering crust has better water-barrier property,and its water-barrier performance model partition is more similar to the vulnerability index evaluation partition,which has a significant effect on the floor evaluation of the security zone.
