摘　　要：溢洪道右导墙产生裂缝的主原因是右导墙一侧有冰、另一侧无冰,形成较大的冰荷载,使右导墙向溢洪道侧变形较大,同时超过导墙允许应力及配筋,故在受力最大处及结构薄弱部位产生裂缝及较大变形。对裂缝产生原因进行了分析并提出了处理措施,供参考。One side of the right guide wall of the spillway at Xueshanhu reservoir was icy while the other side was ice free. The great ice load caused the deformation of the right guide wall towards spillway. Cracks occurred where the maximal stress and the weakest structure existed. The paper analyzed the cause reasons and advanced treatment measures, for reference.
