梁格法在空腹式圬工拱桥加固计算中的应用
Application of grillage method in reinforcement calculation of open-faced arch bridge
摘要
Abstract
At present,the domestic work focus on bridges in service is mainly focused on the evaluation of bearing capacity and reinforcement of old bridges and bridges.The research on the old arch bridges focuses on reinforcement materials and reinforcement methods.The study is less.This paper relies on a fasting concrete arch bridge reinforcement project,uses the grillage method to carry on the finite element analysis,carries on the comparative analysis to the main arch circle's stress performance before and after strengthening the concrete arch bridge reinforcement,the research result has the certain reference value to the concrete arch bridge rein-forcement calculation.关键词
