摘要:
地震诱发的海啸对沿海围护结构的破坏具有强度大的特点。滨水挡土墙作为重要的围护结构,海啸与地震的联合作用极易造成其发生绕墙踵的被动破坏。采用条分法,将土楔体分割成无数平行于破裂面的刚性土条,并建立绕墙踵转动的挡墙与刚性土条之间的速度容许场。基于极限上限理论,依据外力做功功率等于其内能耗散功率,推导了地震加速度系数的表达式。与经典极限平衡理论相比,该方法考虑了挡墙的位移模式,且无需假设地震土压力的作用位置。分析了浪高与海平面高度之比,内摩擦角φ及墙土摩擦角δ对滨水挡土墙稳定性的影响。
Abstract:
The tsunami caused by the earthquake has great damage to the coastal enclosure structure. The waterfront retaining wall is an important enclosure structure. The combined action of tsunami and earthquake will cause passive damage around the heel of the wall. By using the slice method, the soil wedge has been divided into countless rigid soil strips parallel to the fracture surface. The velocity admissible field between the retaining wall and rigid soil bar is established. Based on the limit upper bound theory, the expression of the seismic acceleration coefficient is deduced according to the fact that the external power is equal to the internal energy dissipation power. Compared with the classical limit equilibrium theory, this method considers the displacement mode of the retaining wall and does not need to assume the application location of the e seismic earth pressure. The effects of wave height to sea level height ratio, internal friction angle φ, and wall-soil friction angle δ on the stability of the waterfront retaining wall are analyzed.
