基于可靠性的简支梁承载力评估

Carrying-capacity Assessment of Simple Support Bridge on Reliability

为了对比可靠性评定的结果与现有评估规范评估结果的差异性,依据实例桥梁检测所得数据,按公路桥梁承载能力检测评定规程中配筋混凝土桥梁承载能力极限状态进行检算,运用荷载试验所得的结果对检算模型进行修正,验证了对金沙桥运用可靠性理论进行技术状况评定与现有评估方法是一致的。本文所用的评估过程可供桥梁检测养护工作者在实际工作中参考。

In order to compare the difference between the results of reliability assessment and current assessment standard evaluation,data were obtained by instance bridge detection. The test was carried out according to the concrete bridge hosted capacity limit state in the process of highway bridge hosted capacity detection. The calculation model was modified by applying the load test. It is proved that the technical condition of the sands bridge theory of reliability evaluation is consistent with the current assessment methods. The assessment process in this paper can be used for reference in the bridge test maintenance workers in the practical work.
