摘  要:
大坝开挖支护方案的好坏直接影响整个大坝工程的安全、进度与投资,因此,合理的选择大坝开挖支护方案就显得非常重要。本文根据大坝开挖支护方案所具有的少数据、贫信息、不确定性系统等特征,通过运用灰色系统理论中的灰色关联法,并结合改进的层次分析法,从而对实例大坝开挖支护方案进行量化处理,以得到最优方案。结果表明:层次-灰色分析法科学有效,能在一定程度上指导大坝开挖支护方案的优选工作。

摘  要:
The quality of dam excavation and support directly affects the safety, progress and investment of the whole dam project. Therefore, it is very important to choose a reasonable scheme of dam excavation and support. In order to obtain the optimal scheme, this paper is based on the characteristics of small data, poor information and uncertain system on the project of dam excavation and support, and the grey relational method of grey systme theory was adopted to quantified the support scheme for excavation of dam, combining with improved analytic hierarchy process. The results show that the hierarchy-grey analysis is scientific and effective, which could guide the optimization of support scheme for excavation of dam to a certain extent.
