摘要
利用收集到的WIM(Weight in Motion)卡车荷载数据,开展了建立基于可靠性理论的现有桥梁评估公式研究。通过选取国内8种常见桥梁形式计算出了目前现行桥梁设计规范的隐含可靠指标。结合我国现行桥梁设计规范与公路工程可靠度设计标准,建立了基于可靠性理论的现有桥梁承载力评估公式,结果可为我国已建桥梁评估、新桥设计规范的制定和修改提供一定的参考和对照。
Using the collected WIM （Weight in Motion） data, the research on assessment formula for the carrying capacity of Chinese Bridge based on reliability theory is put forward. Eight common bridges are selected for calculation and the inherent reliability index of the present design code in China is given. Combined with present bridge design code and highway engineering reliability design code in China, the assessment formula for the carrying capacity of Chinese Bridge based on reliability theory is given. The results can offer some reference and gist for the formulation, modification of bridge design codes and assessment codes.
