水利水电工程地质灾害问题的初步研究摘要随着社会经济迅速发展，国家政策方面对我国各种重点水利水电工程的建设也变得也越发重视，水利水电工程建设不仅能够合理分配水资源，还能够避免了一些突发洪涝灾害问题的发生出现，还可以，灌溉农田在确保农业用水方面发挥着重要作用，水利水电工程也确实说是一种直接关系到整个国计民生大事的重大水利工程基础，但是目前水利水电工程项目在实施建设过程中会经常地发生一些小型的地质灾害，比如泥石流、崩塌、滑坡，其中也发生过一些影响比较重大的或者大区域范围内的一些大型地质灾害，会给整个水利工程带来不利影响，因此，本文内容就是主要通过介绍小型流域地质灾害可能产生影响的水文环境特征因素分析方法及灾害基本成因机理的分析，并评估可能产生的地质灾害的风险，从而提出具体的地质灾害的预防措施，帮助减少地质灾害问题对水利水电工程带来的影响，并保障水利水电工程建设顺利进行和后期安全运营。关键词：地质灾害：风险评估：水利水电工程：环境保护：灾害防控技术ABSTRACTWith the rapid development of social economy,national policies have paid moreand more attention to the construction of various key water conservancy andhydropower projects in China.The construction of water conservancy andhydropower projects can not only reasonably allocate water resources,but also avoidsome sudden flood and waterlogging disasters.In addition,irrigated farmland playsan important role in ensuring agricultural water use,Water conservancy andhydropower project is indeed a major water conservancy project foundation directlyrelated to the whole national economy and people's livelihood.However,at present,some small geological disasters,such as debris flow,collapse and landslide,haveoften occurred in the implementation and construction of water conservancy andhydropower projects,among which some major geological disasters or large-scalegeological disasters within a large area have also occurred,which will have anadverse impact on the whole water conservancy project.Therefore,The content ofthis paper is mainly to introduce the analysis method of hydrological environmentcharacteristics and basic cause mechanism of geological disasters in small watershed,and evaluate the risk of possible geological disasters,so as to put forward specificpreventive measures for geological disasters,help reduce the impact of geologicaldisasters on water conservancy and hydropower projects,and ensure the smoothprogress of water conservancy and hydropower project construction and safeoperation in the later stage.Keywords:geological disaster;Risk assessment;Water conservancy andHydropower projects;environmental protection;Disaster prevention and controltechnology目录摘要…ABSTRACT...1第一章绪论，第二章水利水电工程地质灾害特征分析42.1水利水电工程地质灾害发育分类42.2水利水电工程地质灾害成因初步分析…5第三章水利水电工程对环境的影响分析…73.1水利水电工程建设项目对自然环境的影响73.2水利水电工程环境保护措施8第四章水利水电工程地质灾害风险评估…94.1地质灾害危险性评估概念和内容94.2水利工程地质危害风险评估等级和适用范围94.3水利工程实例分析…10第五章水利水电工程地质灾害防控技术和方法1251进行地质勘察，因地制宜工程设计…5.2进行地质评估，落实防控方法…125.3有效保障地质环境的基础上，完善工程建设质量管理制度135.4做好预测预报，进行有效处理13第大章结论致谢…16
