摘要
通过建立三维有限元模型,分析码头前沿设板桩墙及堆载区设低桩承台两种浚深改造方案的效果。经分析可知,码头浚深改造后桩基弯矩增大,幅度最大的为靠近堆载区的桩基。对于码头前沿设板桩墙改造方案,前沿桩基内力减少,但后方临岸侧桩基改善效果很小。对于堆载区设低桩承台的改造方案,后方临岸侧桩基弯矩减小较明显。若将两种方案结合,无论码头前沿桩基还是后方桩基,改善效果均较好。
By establishing a three-dimensional finite element model,the effects of two dredging reconstruction schemes of setting sheet pile walls at the front of the wharf and setting low pile caps in the stacking area are analyzed.The analysis shows that the bending moment of the pile foundation increases after the dredging and reconstruction of the wharf,and the largest magnitude is located in the pile foundation near the stacking area.For the reconstruction plan of the sheet pile wall at the front of the wharf,the internal force of the front pile foundation is reduced,but the improvement of the rear side pile foundation is small.For the reconstruction plan with low pile caps in the stacking area,the bending moment of the pile foundation on the rear bank side is significantly reduced.If the two schemes are combined,no matter the pile foundation at the front of the wharf or that at the rear,the improved effect is better.
