一、裂缝的基本情况白山拱坝泄洪高孔混凝土的浇筑,在高程371米以上,导墙与坝体混凝土是一同浇筑的,形成图1所示的浇筑仓面。原设计意图为利用溢流导墙自重来改善空库情况下游坝面的自重应力。结果,导墙部位发生了一些裂缝。 First, the basic situation of cracks Baishan arch dam spillway high-perforated concrete pouring, at an elevation of 371 meters, the guide wall and dam concrete are poured together to form the casting surface shown in Figure 1. The original design intent is to make use of the gravity of the overflow guide wall to improve the self-weight stress of the downstream dam surface in the case of empty storage. As a result, some cracks occurred in the guide wall.
