病险水库安全诊断与除险加固新技术

New technology of danger inspection and reinforcement of dangerous reservoirs

结合典型病险水库大坝安全诊断和除险加固技术方案的工程实践,研发出深水声像复合查漏、粗粒料取样与钻孔可视化、大坝安全智能评价与管理一体化等安全诊断技术。针对不同的水库病害提出了大流量渗漏通道堵漏、堆石坝变形控制、沥青混凝土心墙坝防渗体重构、面板堆石坝垫层超深斜孔灌浆加密等一系列新技术。工程应用实践表明,所提出的病险水库安全诊断与除险加固技术具有很强的针对性,而且有效、安全、可靠,可供类似病险水库除险加固借鉴。

Combining with practices of danger inspection and reinforcement of typical dangerous reservoirs, we have developed several danger inspection technologies such as sound-image integrated seepage inspection in deep water, sampling of coarse ma-terial and drilling visualization, integrated and intelligent system of evaluation and management for dam safety. Aiming at various dangers of different types of dams, a series of new reinforcement measures were put forward, including blocking for seepage pas-sage with large flow, deformation control of rock-fill dam, reconstruction of anti-seepage body for asphalt concrete core wall dam, grouting consolidation for cushion layer of CFRD by extra-deep inclined holes. The engineering practices proved that the technologies of dangers inspection and reinforcement measures are well-directed and effective, safe and reliable.
