[摘要] 針對(duì)框構(gòu)橋頂進(jìn)施工的安全關(guān)鍵，對(duì)施工期間的線路加固體系進(jìn)行空間受力分析。采用ANSYS軟件建立有限元模型，綜合考慮地基承載力和支座處情況；同時(shí)按施工期間受力情況確定最不利工況情況，考查最不利工況下加固體系的最大豎向位移、最大應(yīng)力為施工提供可靠的數(shù)據(jù)保證；同時(shí)根據(jù)結(jié)構(gòu)特點(diǎn)給出簡(jiǎn)化算法 ，并對(duì)兩者做出比較分析。

Abstract: 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.

Keywords: reinforcement system; space force; numerical and computational analysis
