大跨度钢管混凝土系杆拱桥静载试验研究

摘要

本文以新竣工的下承式钢管混凝土刚架系杆拱桥为背景工程，进行了成桥静载试验。通过实测数据与理论数据相对比分析可知，该桥处于较好的弹性工作状态，为后期使用与管理提供了科学依据。%This paper, taking the newly completed concrete filled steel tubular frame tied arch bridge as the engineering background, carried out the static load test of the bridge. By comparing the measured data with the theoretical data, it can be found that the bridge is in a good state of elasticity, which provides a scientific basis for the use and management of the latter.
