摘　　要：某超长地下室墙体一期施工后出现大量裂缝,从设计角度和施工方案方面分析了裂缝成因,就后浇带设置间距、地下室墙体的配筋方式、混凝土骨料选择及施工组织等方面提出了改进建议,并在地下室墙体二期及后续施工时采用改进方案实施,裂缝数量及宽度得到明显控制.对墙体裂缝采用反应粘技术进行处理,经试水及后期使用检验,表明裂缝处理效果良好,满足了地下室的使用性能.A mass of cracks appear after the 1 st phase construction of an over-length basement. From the angle of design and construction scheme, the causes of cracks are analyzed. We have put forward improvement suggestions on the set of intervals of post-poured strip, reinforcement methods of basement wails, choosing the concrete aggregate as well as construction organization and the number and width of cracks are obviously controlled after improvement schemes are applied in the 2nd phase and following process of construction. In dealing with wall cracks by taking reactive adhesive technology, the result shows that these cracks are controlled effectively by water test and later use and the use performance of basement is well-met.
