| 摘 要： | 为了研究高潮位作用下的海堤抗滑稳定性,通过室内试验得到海堤的物理力学参数,用极限平衡法与有限元强度折减法分析施工期海堤抗滑稳定性。研究发现:某海堤受到高潮位作用,在自重、降雨、波浪、地震等因素的影响下,通过模拟和计算,其迎水坡和背水坡均是稳定的,不存在滑动破坏,但是潮位的快速涨落使得海堤抗滑稳定性下降,潮位越高对海堤的破坏影响越大;同时,在降雨与地震的作用下海堤抗滑稳定性均降低,波浪对于堤身的影响是一个长效机制,在研究中也要着重关注。

| Abstract: | To research the seawalls stability against sliding under high tide level in construction period, limit equilibrium and finite element shear strength reduction methods were used to analyze the stability with the physical and mechanical parameters from indoor tests. Under the effect of self-weight, rainfall, wave and earthquake, a certain seawall under high tide level is stable for both upstream and downstream slopes from simulation results. However, the rapid changes of tide levels may lead to decreasing the stability of seawalls, and the higher the tide level, the bigger impact on seawalls.The rainfall and earthquake may also decrease the stability of seawalls. The long-effect mechanism of the wave to seawall stability should also be focused in the study. |
