摘要
结合具体工程,采用Flac3D软件对筑坝围堰作用下邻近桥下桩基受力特性进行模拟分析。分别研究桩顶荷载施加前后基桩的受力情况,以及随着土体固结时间的推移和围堰荷载的改变、基桩受力性状的变化。分析结果为类似工程的设计施工提供参考依据。
Based on the specific projects, FLAC3D was used to simulate the pile stress character under the action of the dams cofferdam. The stress of the foundation pile was analyzed under load and without the load respectively, and with the passage of the time soil consolidation, the change of the load and the changes of the stress were also analyzed. The results can provide the design and construction of similar projects with reference.
