摘要
应用三维有限元分析,采用增量计算方法,对某围堰工程承台钢板桩围护结构进行了动态施工力学的三维数值模拟。重点分析了施工过程中钢板桩的侧向位移、弯矩、圈梁的弯矩和钢管的支撑轴力等发展规律。研究结果表明,该围堰工程承台钢板桩围护结构设计和施工方案在理论上是安全可行的。
The staged construction mechanics of the steel sheet pile retaining structure for a cofferdam project are numerically simulated using 3D FEM incremental computing method. The lateral displacement and bending moment of the steel sheet pile, the brace bending moment and the steel pipe axial force are emphatically studied. The results indicate that the design of the steel sheet pile retaining structure and the construction scheme of the cofferdam engineering are feasibly in theory.
