摘要
以排水固结处理过的软基上的海堤工程为研究对象,考虑自重及波浪力作用,采用有限元软件ABAQUS建立二维有限元分析模型,计算得到相关的应力场和位移场云图;对塑料排水板处理区的土体进行强度折减以分析对于海堤稳定性的影响并得到相应的塑性区云图。对计算结果进行分析得出:海堤工程上层土体的水平位移对于海堤的整体稳定性有重要影响;建造上部结构之前必须对软基进行预处理;采用强度折减法研究海堤稳定性是可取且实用的。
The seawall project on consolidated drained soft foundations is the research object consideringthe effect of gravity and wave force. The finite element software ABAQUS is used to establish the two-dimen-sional finite element analysis model. Then the related stress fields and displacement fields are calculated. Thestrength of the consolidated drained soil is reduced to analyze the influence on the stability of seawall based onthe plastic zone. Results show that horizontal displacement of the upper soil has an important influence on theoverall stability of seawall. Before the construction of the superstructure, the soft foundation must be pre-treat-ed; and analysis of seawall stability by strength reduction method is desirable and practical.
