混凝土坝,由于施工管理水平不同,其质量与成本都有较大差异。如五十年代我国有不少工程提出大坝内部混凝土的水泥用量有可能降低到110～120公斤/米~3甚至更低,但并未在施工中实现。因为这样低的水泥用量,需要极其严格的施工管理,才能保证质量。回顾建国以来,我国混凝土坝的质量波动情况和水泥单耗,与施工管理水平有着极其密切的关系。总的来说,不注重施工管理,质量事故就多,水泥单耗也随之增加。解放初期,施工经验不多,但在施工管理方面,基本上按照规章制度办事,这一时期的工
Concrete dam, due to different levels of construction management, the quality and cost are quite different. For example, in the 1950s, many projects in our country proposed that the cement content of concrete inside the dam may be reduced to 110-120 kg / m 3 or even lower, but this has not been achieved in construction. Because of such a low amount of cement, the need for extremely strict construction management, to ensure quality. Recalling the founding of our country, China’s concrete dam quality fluctuations and cement consumption, and construction management level has a very close relationship. In general, do not pay attention to construction management, quality and more accidents, cement consumption will also increase. In the early days of liberation, there was not much construction experience, but in terms of construction management, the work basically followed the rules and regulations. During this period,
