溢洪道毕业设计-毕业论文.doc

内 容 摘 要 笔架水库位于四川省眉山市东坡区城东南方17公里处。由于当地河流常常雨后造成山洪，常给农作物和村镇造成灾害，另外，当雨量分布不均时，又易造成干旱现象，因此有关部门对本地区作了多次勘测规划以开发这里的水利资源。经初步论证，该工程拟采用土石坝作为挡水建筑物，岸边溢洪道作为泄水建筑物。本文对土石坝的概念和设计要求进行分析和研究，并对笔架水利枢纽挡、泄水建筑物进行初步设计。关键词：笔架水库 土石坝 初步设计AbstractBiJia reservoir is located in DongPo district of MeiShan City，SiChuan province，17 kilometers to the southeast of the city. Because river there usually causes damage to thecrops and villages by the flash floods after rained, in addition, when the rainfall is not regular, it will be easy to cause drought, so the relevant departments have provided a large amount of surveys for this region to exploit waterpower resources. After generally demonstration,the project is proposed to use earth and rockfill dam as the water retaining structure, the shore spillway as the water release structure.This thesis is mainly to give a analysis and research to the concept and design requirements of earth and rockfill dam, and make a preliminary design for the water retaining structure and the water release structure.Key words: BiJia reservoir rockfill dam preliminary design目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc357759469 1基本资料 PAGEREF _Toc357759469 \h 1 HYPERLINK \l _Toc357759470 2水文 PAGEREF _Toc357759470 \h 2 HYPERLINK \l _Toc357759471 2.1气象 PAGEREF _Toc357759471 \h 2 HYPERLINK \l _Toc357759472 2.2径流 PAGEREF _Toc357759472 \h 2 HYPERLINK \l _Toc357759473 2.3洪水 PAGEREF _Toc357759473 \h 4 HYPERLINK \l _Toc357759474 2.4泥沙 PAGEREF _Toc357759474 \h 9 HYPERLINK \l _Toc357759475 2.5水位-面积及水位-库容关系曲线 PAGEREF _Toc357759475 \h 10 HYPERLINK \l _Toc357759476 3地质 PAGEREF _Toc357759476 \h 12 HYPERLINK \l _Toc357759477 3.1地形地貌 PAGEREF _Toc357759477 \h 12 HYPERLINK \l _Toc357759478 3.2地层岩性 PAGEREF _Toc357759478 \h 12 HYPERLINK \l _Toc357759479 3.3地质构造及地震 PAGEREF _Toc357759479 \h 14 HYPERLINK \l _Toc357759480 3.4库区工程地质条件 PAGEREF _Toc357759480 \h 14 HYPERLINK \l _Toc357759481 3.5坝区工程地质条件及其评价 PAGEREF _Toc357759481 \h 14 HYPERLINK \l _Toc357759482 3.6天然建筑材料 PAGEREF _Toc35775948
