软土地基某桥台产生侧移的成因分析与研究

Cause Analysis and Research on Lateral Displacement of One Bridge Abutment in Soft Soil Foundation

以软土地基某桥梁工程为研究背景,通过现场量测、拍照等方式实地调查其桥台产生的侧移及桩柱开裂情况。在研究过程中,采用大型有限元计算软件建立了三维数值模型,并分析了不同填土固结时间和软土层厚度对桥台桩柱的影响,最后,根据桩身受力和变形规律提出了相应的结论与建议。

Taking the bridge project in soft soil foundation as the research background,the lateral displacement of its bridge abutment and pile cracking were investigated by field measurement,photography and other methods.In the research process,a three-dimensional numerical model was established by using large finite element calculation software,and the influence of different filling consolidation time and soft soil thickness on the bridge abutment and piles was analyzed.Finally,according to the force and deformation law of the pile body,corresponding conclusions and suggestions were put forward.
