Synopsis
《三峡库区高陡岸坡成灾机理研究》首先系统总结了三峡库区各段高陡岸坡倾倒、滑移、剥落和倾倒转滑移等主要的变形破坏现象。基于茅草坡斜坡、龚家坊4#斜坡、箭穿洞危岩体、青石滑坡、横石溪危岩体5处典型高陡变形岸坡的详细调查和长期观测研究，提出三峡库区部分消落带岩体正在劣化，揭示库水波动加速了典型高陡岸坡的变形破坏。这些高陡岸坡失稳的主要致灾模式为涌浪，涌浪灾害影响范围更远更大。建立了三峡库区干流和支流崩滑体涌浪概化模型，开展了大量概化涌浪试验和龚家坊崩滑体缩尺试验，推导形成了刚性块体和散粒体的一系列滑坡涌浪公式，研究了涌浪的三维地貌效应。引入局部水头损失公式，初步建立了可计算全河道涌浪的公式法计算体系。针对崩塌落石和支流滑坡产生的涌浪问题，建立了N-S方程的流体-固体耦合涌浪分析方法。针对长距离、大范围的涌浪灾害问题，构建了基于波浪理论的滑坡涌浪数值计算方法。并利用滑坡涌浪案例进行了各方法的有效性验证。《三峡库区高陡岸坡成灾机理研究》适合水利、工程地质和地质灾害的专业人员使用，也可作为相关专业研究生的专业读本。
