山区岩体移动的Fuzzy预测模型

在全世界范围内，地下开挖岩体移动变形而引起的灾害时有发生；并严重危险人民群众的生命财产安全。而对于此类灾害的研究促进了岩石力学的发展。岩体移动变形及其地面效应的预计问题，是地下开挖活动尤其是采矿过程中所遇到的矿山岩体力学问题中的重要工程课题。由于采矿过程及矿山岩体移动变形这一问题的复杂性，要精确地计算岩体每一点的移动变量是极其困难的。针对山区房柱法采矿岩体变形问题，本文利用Fuzzy数学理论，建立了具体数学模型和预测分析方法。

Fuzzy Prediction Models of Rock Mass Displacements due to Underground Mining in Mountain Areas

The displacement of rock mass due to underground mining has often resulted in major disasters throughout the world, frequently inflicting heavy losses of life and damage to property. And these disasters have motivated the development of rock mass mechanics. The prediction of displacement of rock mass and their surface effects is an important problem of the rock mass mechanics in the excavation activities especially the ore mining. It is difficult to calculate the accurate displacement of every point in a body of rock because of the complexity of the problem. In this paper, fuzzy mathematics models and the prediction methods based on fuzzy measures were applied to the analysis of rock mass deformations due to room-and-pillar mining in mountain areas.
