| 摘 要： | 通过采用ABAQUS有限元软件,建立了沉箱和地基相互作用的三维模型,模拟了在自重作用下沉箱码头墙后土压力分布情况。结果表明:沿码头长度方向由于沉箱舱格及舱格内回填引起各断面结构刚度差异,沉箱墙后土压力分布呈现较为明显的空间特征,其总力较规范计算值偏大,从而使结构稳定性计算偏于不安全。结合工程实例模拟结果提出了一种更为符合实际的墙后土压力计算模型。

| Abstract: | By using the finite element software ABAQUS,a three dimensions model is established which considers interaction between the caisson and the foundation.Besides,this paper simulates caisson wharf rear pressure distribution under the action of gravity.The result shows that stiffness difference in the direction along the wharf length is caused by the caisson cell and cell backfill in each section,and caisson rear earth pressure distribution appears relatively obvious space characteristic,in the meantime the total force is larger than the calculated value by design codes,which makes the stability of the structure is less securable.Combining with simulation results of engineering examples,a practical and reasonable calculation model of the rear earth pressure is proposed. |
