预应力混凝土简支空心板梁桥静载校验系数分析

以内蒙古呼伦贝尔市境内的上护林大桥为工程背景,在预应力混凝土空心板桥的常规静载试验的基础上,提出断面应变校验系数的概念。结合常规校验系数与断面应变校验系数对该桥的工作状况进行评估,得出该桥横向联系及整体工作状况良好,且断面应变校验系数法可以在类似结构桥梁的荷载试验结果分析中加以推广和应用。

Analysis on static load testing coefficient of prestressed concrete simply-supported and voided slab beam bridge

Shanghulin Bridge in Hulunbuir,Inner Mongolia as engineering background,on the basis of conventional static load test of prestressed concrete voided slab bridge,the concept of section strain testing coefficient is proposed.This paper assesses working condition of this bridge combining with conventional testing coefficient and section strain testing coefficient,obtained horizontal linkage and overall job status of this bridge is good,and section strain testing coefficient method can be popularized and applied in analysis of load test results of similar bridge structure.
