摘要
通过3D弹塑性有限元数值仿真模拟,对某交叉口复杂路基边坡在天然状态、钻孔灌注桩状态及钻孔灌注桩+填土+承台式挡土墙支挡状态干、湿条件下的变形行为进行深入分析。根据数值分析结果提出新建道路挡土墙与已建高架路间预留伸缩缝宽度应大于10.0 cm的建议,为道路设计和施工提供依据。
Based on 3D elastic-plastic finite element numerical simulation,this paper carries out deep analysis for slope deformation behavior of complicated roadbed at some crossing under dry and wet conditions in natural state,bored cast-in-situ pile state and bored cast-in-situ pile+filling soil+bearing platform type retaining wall state.According to the results of numerical analysis a recommendation is put forward that the width of reserved expansion joints between the retaining wall of newly constructed road and constructed elevated road should be more than 10.0cm,providing the basis for design and construction of roads.
