枢纽工程重要构筑物(群)与地质环境互馈作用机制与控制技术

Control technology and interaction mechanism between important structures of multi-purpose projects and geological environment

  • 摘要: 紧密结合中国重大水利水电工程长期安全调控的迫切需求,深入研究开挖卸荷、水库蓄水、水位交变、泄洪雨雾及库区气候变化条件下,库区及枢纽区渗流场、应力场和参数场(岩土力学性能参数、加固系统功能指标)的动态演化和耦合作用机理,建立并形成了地质环境变化趋势预测的理论和方法;系统研究不同构筑物(库岸边坡、高坝岩基和大型地下洞室群)与地质环境的互馈作用机制,完善并发展了基于地质环境演化的构筑物工作性状动态分析方法和调控技术,研发了与变化环境相适应的加固系统(特别是锚固体系)长效延寿成套装备与工法,并在实际工程中得到示范应用。

     

    Abstract: Closely inline with the urgent needs of long-term safety regulation of major water conservancy and hydropower projects in China, the dynamic evolution and coupling mechanism of seepage field, stress field and parameter field (geotechnical mechanical performance parameters and functional indexes of reinforcement system) in the reservoir area and project area are deeply studied under the conditions of excavation and unloading, reservoir water storage, water level alternation, flood discharge rain and fog and climate change in the reservoir area, and the theory and method for predicting the change trend of geological environment are established and formed. The mutual feeding mechanism between different structures (reservoir bank slope, high dam rock foundation and large underground cavern group) and the geological environment is systematically studied, the dynamic analysis method and regulation technology of working properties of structures are improved and developed based on the evolution of geological environment, and the complete set of long-term life extension equipment and construction method of reinforcement system (especially anchorage system) adapted to the changing environment is developed, and it is demonstrated and applied in practical engineering.
