摘 要:针对临近既有桥梁的后建工程在施工期间引起的河岸边地质条件变化,及其对桥梁造成的不利影响,通过分析桥梁观测点的位移量及沉降量,明确了影响既有桥梁稳定性的原因,指出了桥梁出现的主要病害,如桥墩顺桥偏移量较大、桥墩和桩基承载能力不足、桥墩开裂等,并设计了相应的维修加固方案。研究结果对评估河岸边后建工程对既有桥梁的影响及设计相应处置方案具有重要工程意义。
Abstract: In response to the geological changes along the riverbank caused by the construction of the adjacent post construction project of the existing bridge, as well as its adverse effects on the bridge, the reasons affecting the stability of the existing bridge are identified by analyzing the displacement and settlement of the bridge observation points. The main diseases of the bridge are pointed out, such as large displacement of the bridge piers along the bridge, insufficient bearing capacity of the bridge piers and pile foundations, and cracking of the bridge piers, and corresponding maintenance and reinforcement plans are designed. The research results have important engineering significance for evaluating the impact of subsequent riverbank projects on existing bridges and designing appropriate treatment plans.
