摘要

本研究采用有限元软件Midas Civil对单塔双索面斜拉桥进行了详细的模型构建,以索同坡黄河特大桥为案例,探究斜拉索索力在环境温度变化下的变化情况.通过模拟分析可知,随着温度的升高,斜拉索的索力也会随之下降;反之,温度的降低会使索力增大.这一发现为斜拉桥的设计与施工提供了科学依据,特别是在考虑温度效应方面.此外,研究还强调了温度监控在维护斜拉桥结构安全中的重要性,建议在桥梁管理中加强对环境温度变化的实时监控,以预防由温度变化引起的潜在结构问题.本研究不仅深化了对斜拉桥温度敏感性的理解,而且为桥梁工程领域提供了重要的参考资料和实践指导.

Abstract

This study used the finite element software Midas Civil to construct a detailed model of a single tower double cable plane cable-stayed bridge.Taking the Suotongpo Yellow River Extra-large Bridge as a case study,the changes in cable force of the cable-stayed bridge under environmental temperature changes are explored.Through simulation analysis,it can be concluded that as the temperature increases,the cable force of the inclined cable will also decrease;on the contrary,a decrease in temperature will increase the cable force.This discovery provides a scientific basis for the design and construction of cable-stayed bridges,especially in considering temperature effects.In addition,the study emphasizes the importance of temperature monitoring in maintaining the safety of cable-stayed bridge structures,and suggests strengthening real-time monitoring of environmental temperature changes in bridge management,to prevent potential structural problems caused by temperature changes.This study not only deepens the understanding of temperature sensitivity of cable-stayed bridges,but also provides important reference materials and practical guidance for the field of bridge engineering.
