摘要
运用结构时变可靠度理论,研究现役桥梁结构可靠度随时间的变化规律,根据桥梁结构时变可靠度,对现役桥梁结构的现状进行评估;根据桥梁结构可靠度的时变规律,对现役桥梁结构的剩余寿命进行预测。结论表明,运用时变可靠度理论研究现役桥梁的时变可靠度,具有很大的理论和现实价值。
In this paper, a method of existing bridges evaluation and service life prediction based on time-dependent reliability theory is presented. Author studies the variety regular of existing bridges reliability and evaluates it based on time-dependent reliability theory. Author also predicts the service Life based on the variety regular of existing bridges reliability. The result demonstrates that it is a practical method.
