| 摘 要： | 本文针对岩土工程稳定性分析，提出了监测、灰色预测和有限单元法相结合的分析方法。建立GM（1，1）模型，用Java语言编写灰色预测程序，在灰色预测基础上，建立了三维弹塑性有限元模型，对局部区域用ANSYS软件进行稳定性分析。应用此方法分析了安庆铜矿围岩的稳定性，灰色预测结果与后续监测结果基本一致，说明模型、程序及所提方法的实用性。

| Abstract: | Aiming at the stability analysis in rock and soil engineering, a method combining monitoring, gray prediction with FEM is presented in this paper. At first, a GM(1, 1, model is established, and a gray prediction program is built with Java language, then by analysing the predicted results, a three-dimensional elastoplastic finite element model is established and the stability in the regional area is analysed by using the ANSYS software. The stability of the surrounding rock in Aanqing Copper Mine is analysed by using this method. The predicted results agree approximately with the following monitored results, indicating the precticability of the model, program and the method. |
