摘要
针对框构桥顶进施工的安全关键,对施工期间的线路加固体系进行空间受力分析。采用ANSYS软件建立有限元模型,综合考虑地基承载力和支座处情况;同时按施工期间受力情况确定最不利工况情况,考查最不利工况下加固体系的最大竖向位移、最大应力为施工提供可靠的数据保证;同时根据结构特点给出简化算法,并对两者做出比较分析。
Considering bridge jacking frame security key,make spatial analysis about reinforcement of the line during construction system. Using ANSYS finite element model of the software and considering the situation at the foundation bearing capacity and bearing; At the same time by the forces during construction to determine the worst case conditions,to provide reliable data for the construction to ensure the paper examine the most unfavorable conditions the maximum vertical displacement of reinforcement system,the maximum stress; Give simplified algorithm based on structural characteristics and make a comparative analysis between them.
