城际铁路单箱双室预制箱梁静载试验研究

文章以海南东环铁路万宁制梁场整孔箱梁静载试验为基础,对城际铁路单箱双室新型预制梁体静载弯曲试验和梁端静载试验进行阐述,重点对静载加载形式、试验测点布置和测试结果进行了描述,最终通过应力应变实测值与理论值的比较,提出试验结论和建议,并对单箱双室整孔箱梁的设计、施工工艺、施工质量以及箱梁的抗裂性能、梁端受力性能进行验证。

Study on City Express Railway's Simple-box Double-cell Prefabricated Box Girder Static Loading Experiment

Based on the Wanning Girder-fabricating Plant' s full span box girder static loading experiment,this article elaborates city express railway's simple-box double-cell prefabricated girder static loading and bending experiment as well as beam ends static loading experiment.This article pays special efforts on describing static loading forms,the arrangement of measured points and test result.At last,through comparing the measured value and theoretical value of stress-strain,this article brings up the conclusio...
