摘　　要：针对重庆市某特大桥主引桥在施工过程中轻轨承重梁的0#块、横梁和墩身等重要部位出现的裂缝分析其成因,并提出处理措施.采用压力灌胶法修补裂缝.经长期观测,裂纹发展得到有效抑制,达到了预期效果和目的.In view of the principal approach span of a super major bridge in Chongqing, this paper analyses the causes of cracks developing in construction on the important locations of the light rail load-bearing beams, such as the blocks 0# , cross beams and pier shafts, and puts forward appropriate disposition measures. Cracks are patched by the method of pressure encapsulating compound. After long-term observations, the expansion of cracks has proved to be effectively controlled, which attains the expected results and objectives.
