摘　　要：本文以系统论和控制论为指导分析了大瑶山燧道岩溶涌水系统。通过利用地质结构特征、水化学场和同位素场的综合信息分析,详细阐述了岩溶涌水的补给来源和范围以及水动力的补排关系。建立了较逼真的岩溶涌水水文地质模型和数学模型,并对涌水过程进行了数值模拟分析。最后分析了涌水所造成的地面塌陷机理并给出其整治方案。The Karst water inflow system is analysed by using systematical and cybernetic methods in this paper. Using the data of geologic configuration, hydrochemical field and isotopic field to synthesize the relevant information, we set forth the feeding source and range of karst pouring water and the relationship between supplying and draining in detail. The hydrogeological conceptual model and mathematical model for karst water inflow are estabilished more realistically, and its pouring process is simulated numerically. Finally, we study the mechanism of surface collapse caused by water pouring and put forth its treatment project for ensuring the safety of railway transportation.
