桥梁是公路网重要组成部分,承担着联结和跨越地面河流等重要要作用,其通行安全是保证公路路网安全的重要因素。桥梁在长期的使用过程中有些人为因素与自然灾害会导致桥梁本身出现损伤与老化。因为这些损伤有时会危及桥梁本身的交通通行安全,所以要进行专业化鉴别来确定桥梁是否能够适应当前的交通量运输任务并保证通行安全。
The bridge is an important part of the road network, which plays an important role in connecting and leaping over the river. The traffic safety is an important factor to ensure the safety of the road network. Some man-made factors and natural disasters during the long-term use of the bridge can lead to the bridge itself being damaged and aged. Because these injuries sometimes endanger the traffic safety of the bridge itself, specialized identification is required to determine whether the bridge can accommodate the current traffic volume and to ensure traffic safety.
