1、大学本科毕业设计（论文） 1 中文摘要 重力坝作为我国最常见的一种坝型，对其进行风险研究的重要性可想而知。近几年，国内 外对于该领域的研究讨论十分激烈。目前，针对坝体工程的风险评估以及可靠性设计已经 成为比较有创新点的论题1。本文就是在这样的背景下，对于重力坝的风险评估方法进行 了初步探究。 本文分为两大部分，本文大概分为两个部分，前半部分为重力坝的设计部分，重点对重力 坝的非溢流坝段进行了计算，另外，对于其细部构造也进行大概的设计。下部分为对该重 力坝方案进行了风险评估，最终得出的结论是该方案风险较低。 本文介绍了风险评估的各种方法之后，结合案例本身，采用了层次分析法对重力坝的风险 进行了评

2、估，其中考虑到了设计、施工、运行、经济、环境等多种因素，又重点对每个子 目标下面的几个属性分别作了研究，最后得出各个子属性的权重数值，再根据该方案在各 个属性下得到了评估分数，综合测评该重力坝方案的风险性。最后，较全面的对于影响重 力坝稳定的因素都做了分析，得出结论。 关键词：重力坝 风险评估 层次分析法 重力坝设计 工程风险 大学本科毕业设计（论文） 本文来自毕设资料网（）2 ABSTRACT Gravity dam in China as one of the most common type of dam, on the importance of risk research.

3、 In recent years, domestic and foreign research about the field discussion is very fierce. At present, in view of the dam engineering risk assessment and reliability has become a more innovative design thesis 1. This article is in this context, for gravity dam risk evaluation method has carried on t

4、he preliminary exploration. This article is divided into two parts, the first part is the design of gravity dam sections, focusing on the computation of gravity dam.In addition,it is for the detail structure and general design. Lower part is divided into the risk assessment scheme of the gravity dam

5、.Finally ,we can conclude that the scheme risk is low. After assessment methods has been introduced in this paper, combining with the case itself, using the analytic hierarchy process (AHP) to evaluate the risk of gravity dam, which took the design into account,such as construction and operation, ec

6、onomic, environmental .I focus on the following attributes to each target which were studied respectively, and finally I conclude that the weight of each attribute value.Again, under each attribute which is according to the scheme evaluation scores, comprehensive evaluation of the gravity dam about project risk has been made. Finally, the comprehensive factors affecting the gravity dam stability have been made analysis.We can draw the conclusion. Keywords: analytic hierarchy process (ahp) gravity dam design
