| 摘 要： | 对长江某穿越工程的钢筋混凝土沉井井壁开裂和变形进行了分析，在现场进行了检测，对钢筋的规格和井壁受力状况进行了计(验)算．分析、检测和计(验)算结果表明：井壁开裂和变形的原因是由于设计计算及配筋不当所致．提出了采用高压喷射环氧树脂液修补裂缝及筑构钢筋混凝土墙加固井壁的措施．

| Abstract: | A discussion is made over the cracking an d deformation in the wall of a reinforced concrete sunk well in a project stretchi ng across the Yangtze River.An on-site examination was made,in which the standa rd of the steel bars and the stressed state of the well wall were checked.The re sults showed that the causes of the cracking and deformation were the wrong desi gning calculations and the wrong placing of the steel bars.The authors sugg est that epoxide resin glue be used in the cracks and the well wall be strengthe ned by a new wall of reinforced concrete. |
