蓝烟铁路公铁立交工程所涉及的斜交连续梁顶升施工,在工程实践中较为罕见,理论研究也多为空白,为解决该改造方案中的技术难点,采用有限元软件Ansys对主桥顶升过程进行了仿真分析,通过比选确定了千斤顶的布置方案,明确顶升过程必须以位移控制为主,力控制为辅,可为顶升施工监控中控制参数的设置提供理论依据。 Lantian railway overpass project involved in the construction of skewed continuous beam jacking in engineering practice is relatively rare, the theoretical research is mostly blank, in order to solve the technical transformation of the technical difficulties, the use of finite element software Ansys on the main bridge jacking The simulation of the process was carried out. The layout of the jacks was determined through comparison and selection. It was pointed out that the jacking process must be dominated by displacement control and supplemented by force control, which can provide theoretical basis for the setting of control parameters in jacking construction monitoring.
