摘　　要：随着我国交通水平的增长,矿区公路桥梁的可靠性逐渐受到了人们的重视,因为矿区公路桥梁受长期矿业开采影响,其地质情况容易出现松动等不良问题,此时其安全性相对较低,同时在交通层面上,车辆行驶时造成的荷载效应会对矿区公路桥梁地基造成扰动,结合其地质情况的不良表现,可能引发安全事故,对此在安全原则上,有必要对矿区公路桥梁的可靠度进行评估。With the increase of traffic level in China,the reliability of highway bridges in mining areas has gradually received attention. Because the highway bridges in mining areas are affected by long-term mining,their geological conditions are prone to loose problems,etc.,at this time,their safety is relatively high. At the same time,at the traffic level,the load effect caused by the vehicle driving will cause disturbance to the road bridge foundation in the mining area. Combined with the poor performance of its geological conditions,it may cause a safety accident. For safety reasons,it is necessary to assess the reliability of road bridges in mining areas.
