摘要
微顶管技术在市政工程中的应用已经非常成熟,但目前针对钢沉井的受力分析缺乏技术规范和成熟软件可用,就此问题采用数值分析的方法展开研究。钢沉井在施工及回收的过程中会产生不同程度的变形,引入不圆度的概念用以表示钢沉井的变形程度。钢沉井一侧为车行道,另一侧为非机动车道,两侧选用不同的地面活荷载。采用ABAQUS有限元软件建立钢沉井的受力分析模型,分析在不同不圆度和深度下钢沉井的应力和变形的变化规律。
The application of micro pipe jacking technology has deeply developed.However,there is currently a lack of technical code and engineering software available for the stress analysis of steel open caisson.The numerical analysis method is used to study this issue.In the process of construction and recovery,the steel caisson will produce different degrees of deformation.Out-of-roundness is introduced to indicate the degree of deformation of steel open caisson.One side of the steel caisson is a roadway,and the other side is a non-motorized lane.Different ground live loads are applied on both sides of the steel open caisson.The force analysis model of steel caisson is established by ABAQUS finite element software.The variation law of stress and deformation was analyzed based on different out-of-roundness and depth of steel open caisson.
