混凝土面板堆石坝毕业设计.docx

山东科技大学学士学位论文 摘 要 混凝土面板堆石坝是用堆石或砂砾石分层碾压填筑成坝体，迎水面用混凝土面板作防渗体的坝，它对地形和地质条件都有较强的适应能力，并且施工方便、投资省、工期短、运行安全、抗震性好，因而其作为坝型选择具有很大的优势。通过地质地形，库区经济，料场位置及材料的分析，最终确定大坝为混凝土面板堆石坝。 混凝土面板堆石坝作为一种特殊的土石坝，主要由堆石体和防渗系统组成，即：面板、趾板、垫层、过渡层、主堆石区和次堆石区。本文扼要介绍设计中进行的主要工作和设计成果：调洪演算、枢纽布置、坝体分区及坝料设计、坝体渗流及稳定分析、坝体沉降计算、坝体的细部构造以及地基处理、泄洪隧洞的设计等。 关键词：混凝土面板堆石坝 调洪演算 坝体设计 渗流计算 稳定验算 隧洞 ABSTRACT With concrete panels as impervious body on the upstream side, concrete face rockfill dam is layered with rubble or gravel and compacted into rockfill dam .Because of its strong ability to adapt to the terrain and geological conditions, convenient construction, less investment, short construction period, operation safety and good earthquake resistance, concrete face rockfill dam has a great advantage to be as a selection of dam type. Concrete face rockfill dam as a special kind of earth-rock dam, is mainly composed of rockfill and impervious system, namely: panel, toe board, cushion layer, transition layer, main rockfill zone and secondary rockfill zone. This paper briefly introduced the main design and the design results: flood regulating calculation, layout, dam zoning and dam design, dam seepage and stability analysis, settlement calculation, the dam structure and foundation treatment, release flood waters tunnel design etc. Keywords: concrete face rockfill dam, flood routing, design of dam body ,seepage calculation, stability calculation, tunnel 目录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc358804304 1. 基本资料和要求  PAGEREF _Toc358804304 \h 1  HYPERLINK \l _Toc358804305 1.1大龙河水电站基本工程资料  PAGEREF _Toc358804305 \h 1  HYPERLINK \l _Toc358804306 1.2 设计工作要求  PAGEREF _Toc358804306 \h 6  HYPERLINK \l _Toc358804307 2. 洪水调节计算  PAGEREF _Toc358804307 \h 7  HYPERLINK \l _Toc358804308 2.1 调洪演算  PAGEREF _Toc358804308 \h 7  HYPERLINK \l _Toc358804309 2.2 方案选择  PAGEREF _Toc358804309 \h 32  HYPERLINK \l _Toc358804310 3.坝址选择及枢纽布置  PAGEREF _Toc358804310 \h 33  HYPERLINK \l _Toc358804311 3.1 坝址及坝型选择
