摘要
对病险水库进行除险加固,可恢复或加强水库的防洪功能及兴利效益,改善生态环境,有利于促进水利事业的发展,更好地造福于人民。病险水库事关人民群众生命财产安全,事关国民经济发展和社会稳定,病险水库的除险加固是十分必要和紧迫的。
     册田水库是桑干河干流上山西省出境处控制性工程,水库工程于1958年3月开始修建,1970年至1976年续建,最大坝高41.5m。水库枢纽工程由大坝、正常溢洪道、浆砌石重力坝等组成,1991年增建溢洪道一座,大坝分为主坝和南、北副坝三段。由于大坝施工前坝基未作彻底处理,水库蓄水后坝基渗漏严重,影响大坝安全;施工过程中大坝填筑质量较差,坝体出现过许多裂缝,水库存在许多隐患。为了提高水库的防洪蓄水能力,充分发挥水库效益,需对水库大坝进行加固。
     通过大坝坝坡稳定、渗透稳定进行了分析,提出上游坝坡从坝轴线开始以1:1.2的坡度开挖至951.0m高程后,用石渣进行回填处理,回填石渣设计干重度21kN/m3,在石渣培厚体与坝体土之间设置反滤层,护坡用干砌石,厚度为40cm,其下设30cm厚碎石垫层。主坝坝基作垂直防渗处理,采用塑性混凝土,防渗墙深入玄武岩4m,防渗墙厚度0.8m。
     南副坝坝基为一古河道,其底部高于现河床10m左右,最大堆积物厚度25m。依据《水利水电工程地质勘察规范》GB50287-99和《建筑抗震设计规范》GB50011-2001评价,南副坝坝基土为液化土层,采用坝前加载法消除坝基液化。
     根据工程所在地区的自然环境、社会环境以及工程施工对环境可能造成的影响,提出了环境保护措施、环境管理与监测计划。
It is very important to shore up reservoirs in poor condition in order to fully display their benefits. Because, once the poor reservoirs are reinforced, they can recover or strengthen the flood controlling capacity and promote the social benefits, improve the ecological environment, promote the development of water conservancy undertakings and bring benefits to the people. And also because they have influence on ensuring the safety of the lives and property of the people, and on accelerating economic development and social stability.
     The Cetinan reservoir is the controlling engineering of departure terminal of Shanxi Province for the mainstream of Sanggan Water. The construction of the reservoir started in March 1958, and it was continuing to construct from 1970 to 1976, the most height of the dam is 41.5 maters. The hub project of the reservoir is composed of big dam, normal spillway, cemented masonry gravity dam and so on, and later a spillway was constructed too. The dam consists of main dam, north and south secondary dam. The dam still has many potential problems due to so badly searched before construction that the seepage is very serious after the reservoir water storing, and because of so poor quality of filling the dam that many cracks is arising in the dam body. In order to improve the anti-flood and water storage capacity, and fully displaying the benefits, it is urgent to reinforce the dam of the reservoir.
     By means of analyzing the slope and infiltration stability of the dam, many measurements are put forward. The upper dam slope was excavated with the slope of 1:1.2 ratio from the axis to the height of 951 meters, it was filled with broken stones of which design dry density is 21kN/m3, the reverse filter layer was installed between the broken stones form and dam body, the revetment was filled up with broken stones, which was 40 cm in thickness, and under it the later layer was constructed with 30 cm thick broken stones. The main dam foundation was handled with plastic concrete in a vertical position, which was called as diaphragm wall with 4 meters thick and thorough into the basalt.
     The foundation of southern assistant dam was an ancient river channel, the bottom of which was 10 meters higher than the riverbed, the maximum thickness of the accumulation was 25 meters. According to the evaluation of << Water Conservancy and Hydroelectric Power Engineering Geological Investigation Standards>>GB50287-99 and the <>GB50011-2001, the foundation of southern assistant dam was a liquefaction layer, which could eliminated liquefaction stability for earth dam by using loading method in front of dam.
     Environmental protection measurements, environment management and monitoring program were posed according to its natural and social environment of the engineering and the impact of engineering construction on environment.
