| 摘 要： | 以实际工程为依托,采用有限元数值分析方法,对桩锚支护结构后侧土体局部地基处理后的土压力分布特征进行反演分析,研究地表荷载、航道开挖深度、软土地基置换率、地基处理宽度、深度对支护结构后侧土压力分布特征的影响。结果表明,通过对堤岸侧土体进行地基处理,不仅改变了原有地层土压力的分布特征,而且可有效减小地基处理范围内的土压力值。所得结论对软土堤岸工程的支护设计具有重要的参考价值。

| Abstract: | Based on the actual project,inversion analysis on the distribution characteristics of earth pressure has been carried out by adopting the finite element method for the locally improved soil behind pileanchor supporting structure.Study has been executed on the effect of local soil improvement on earth pressure,such as the effect of surface load,excavation depth of waterway,replacement ratio of composite foundation,strengthening width and depth of local soil improvement.The analysis results show that the distribution characteristics of earth pressure of primary formation has been not only changed,but also the earth pressure value in the range of soil improvement has been effectively decreased.The conclusion of this paper has important reference value for design of supporting engineering in soft soil area. |
