| 摘 要： | 通过采用ABAQUS有限元软件进行数值模拟,主要研究了考虑稳定渗流和波浪力作用下内河航道岸坡的稳定性。根据广西壮族自治区右江上游那吉库区岸坡整治工程数值模拟研究项目的要求,分别对岸坡在稳定渗流、波浪力和两者共同作用下的情况建立了数值模型,分析不同工况下岸坡的稳定性;并采用强度折减法求得安全系数,将结果与基于传统极限平衡理论的Morgenstern-Price法进行对比,来验证其可靠性。

| Abstract: | Inland river waterway slope stability under seepage and wave pressure was mainly researched in this paper.The ABAQUS finite element program was adopted to carry out numerical simulations.Numerical models were set up for slope under different conditions of steady seepage,wave pressure and their combination to analyze the slope stability,and the strength reduction FEM was also used to get the safety factor.Meanwhile,the results were compared with Morgenstern-Price method based on the traditional limit equilibrium theory to verify its accuracy. |
