摘要
对讷河大桥现场检测的基础上,对其进行技术评定,并采用一次二阶矩理论的验算点法对讷河大桥在单元时段内的失效概率进行了估计。根据剩余使用期内的失效概率与单元时段内失效概率的简单比例关系,对该桥梁剩余使用期内的失效概率进行估计。
The technical appraisement of Nehe Bridge was made by checking and measuring its load bearing capacity on the spot. The failure probability per unit time of the bridge was estimated by the method of checking computation point from first-order second moment theory. Furthermore, the failure probability during the remaining lifespan of the bridge is calculated in terms of the simple relationship of the failure probability between remaining lifespan and per unit time.
