| 摘 要： | 运用大型有限元软件建立三维有限元模型，模拟钢板桩码头施工过程中板桩的桩身侧向位移、桩身土压力以及桩身弯矩的变化规律，从而了解施工过程中钢板桩的受力情况。研究结果表明：随着抛填施工的进行，板桩墙的侧向位移逐渐增大，呈两头小、中间大的侧移趋势；板桩墙侧土压力沿深度方向均呈缓慢的增大趋势，最大土压力为激活板桩墙及后侧回填土工序墙底部的152.1 kPa；板桩墙由于上端受拉杆约束、下端受土体嵌固作用，弯矩大体呈“S”。

| Abstract: | The large-scale finite element software is applied to establish a three-dimensional finite element model and simulate the lateral displacement,soil pressure and moment of pile body so as to understand the stress condition of steel sheet pile in the process of construction.The result shows that along with the filling construction,the lateral displacement of sheet pile wall increases gradually,and that in the middle is larger than at both sides;the lateral soil pressure of sheet pile wall increases gradually along the depth direction;the maximum soil pressure appears at the bottom of the wall of 152.1 kPa;the top of the sheet pile wall is bound by pull rod and the bottom is embedded in the soil,which makes the moment S-type. |
