白石水库工程建设中新技术的研究与应用

白石坝坝址位于气候条件恶劣的北方严守地区，坝体结构复杂，为此开展了一系列攻关课题的研究，并应用到白石水库工程建设中，其内容包括：（１）对施工导流进行风险决策分析；（２）将ＲＣＣ配合比用于ＲＣＤ施工，发展了碾压混凝土筑坝技术；（３）底孔采用全过程仿真计算技术进行设计；（４）溢流坝采用异型宽尾墩挑流消能；（５）在坝体越冬层面上下游采取预留缝措施；（６）对旧ＳＤＭＱ１２６０／６０型门机进行技术改造；（７

Research and Application of New Techniques in the Construction of Baishi Reservoir

The Baishi Dam is located in severe cold northern area of China, with a complicated structure. Therefore, a series of new techniques were researched and adopted to the Baishi Dam, including:(1) To adopt risk decision analysis for construction diversion; (2) To apply the RCC mix to the RCD construction so as to make roller compacted concrete dam technique developed;(3) To design the bottom outlets with the all process emulation calculation;(4) To use the fashion flaring piers in spillway dam;(5) To take the measure of pre leaving cracks on the upstream and downstream sides of the overwintering faces of dam;(6) To transform technically the old SDMQ 1260/60 portal crane;(7) To adopt the monoblock suspension and two way symmetry slip form;and (8)To probe into theoretically and practice GIN grouting method. The project practice shows that the remarkable benefits were gained from these new techniques.
