水库大坝设计 水利工程专业毕业设计 毕业论文.docxVIP

摘要新春水库位于四川省江油市东兴乡新春村，属涪江水系芙蓉溪支流。新春水库自然集雨面积3.13km2，坝址以上主河道长5.17km，河槽比降12.53‰。大坝下游1.2km处有108国道，影响人口约800人，耕地1200亩。工程于1973年动工修建，1975年建成投入使用，是一座以灌溉为主，兼有防洪、养殖等综合效益的小（2）型水库。由于5.12地震对水库造成一定程度的损伤，如：①坝体产生多条裂缝。②下游有渗漏现象，大坝迎水坡未进行防护，水流掏涮严重；坝顶未硬化，不利于工程管理和大坝安全。③原放水设施为斜卧管，浆砌条石结构，有渗漏，且运行管理不便。本次设计的主要内容为：通过对新春水库复核基本资料为水文设计洪水复核、洪峰流量以及溢洪道最大泄洪能力复核、大坝渗流稳定分析、除险加固方案设计、施工组织设计等。通过水文方面计算，试算出设计和校核水位，最后进行溢洪道最大泄流能力复核，另外通过大坝的渗流稳定分析确定大坝是否存在险情并采取有效的工程措施，从而使大坝达到除险加固的目的。关键词：水文计算；稳定分析；渗流分析；稳定分析；除险加固AbstractXinChun reservoir is located in Sichuan Jiangyou Dongxing XinChun village of the Peijiang River Lotus River tributaries. Natural rain collection area of ??the reservoir is 3.13km2, the main water rain collection area of natural runoff storage store. The main river above the dam site long 5.17km, channel slope 12.53 ‰. Dam has an influence of a population of about 800 people and 1200 acres of farmland. Project started construction in 1973 and put into operation in 1975. It is a mainly for irrigation, flood control, water supply, farming and the small overall efficiency (2) reservoir.朗读显示对应的拉丁字符的拼音?字典 The 5.12 of the reservoir as a result of the earthquake caused damage to some extent, such as: (1)there are a number of cracks in the dam; (2) leakage downstream dam slope is not welcome for water protection, water rinse dig grave; top of the dam is not hardened, not conducive to project management and dam safety. (3) the original drainage facilities decumbens tube, mortar of stone structure, leakage, and the operation and management of inconvenience. The main elements of design, including review of hydrological design flood, peak flow, as well as review of the flood largest discharge capacity of the spillway ,dam seepage and stability analysis, eliminating and reinforcement design, organized construction design, etc.朗显示对应的拉丁字符的?Through the hydrological aspects of computing, we can design and verification test to calculate the water level, and finally the maximum spillway discharge capacity to review.
