钢筋混凝土支撑轴力影响因素研究

摘要

文章基于钢弦式钢筋应力计工作原理,对广西大学地铁车站深基坑第一道支撑中包含的钢筋混凝土支撑及钢支撑轴力进行对比分析,并通过有限元模拟对支撑轴力测试结果进行验证,从理论上分析影响混凝土支撑轴力的几种因素,得出实际钢筋混凝土支撑轴力约为测试结果的30%。%Based on the working principles of vibrating wire rebar stress meter,the article conducted the comparative analysis on the reinforced concrete support and steel support axial force included in the first support of deep foundation pit at Guangxi University subway station,verified the support axial force through finite element simulation,theoretically analy-zed several factors that affect the concrete support axial force,and got the result that the actual reinforced concrete support axial force is about 30% of the test result.
