| 摘 要： | 应用作者近年来在岩体动态施工力学方面的研究成果，从岩体稳定角度出发，考虑现场施工的约束条件，采用将人工智能语言与有限元程序结合起来的智能化系统，对小浪底水利工程地下厂房洞室群施工顺序做了优化分析，克服了以前动态规划每级计算中只考虑开挖１个分块的缺陷，在众多可能方案中，得到６种优化方案．经比较，每种方案都比原方案围岩稳定性有较大提高，对实际工程具有参考价值．

| Abstract: | On the basis of rock mass safety and research of rock mass mechanics in dynamic excavation and the restraining conditions at site optimization of constructional sequence is made by an intelligent system which combines artificial intelligent language and FEM program for excavation of Xiaolangdi water conservancy project.Six optimal proposals are obtained from a lot of possible proposals.It has overcome the disadvantage of the primary planning in which only one block is excavated in each level of calculation.It is found that the safety of any proposal is remarkably improved than that of the primary proposal.It is no doubt that this is of reference value to the actual projects. |
