李津身同志在“水力发电”提出装配式空心坝的问题我认为是今后改进重力坝的一个方向。不过本人对李同志所提出的单元构件及其砌筑法有一点意见。我认为单元构件(简称元件)采用正方形,施工比较简单,这样元件本身在重力坝中可以满足应力及强度的要求,因为重力坝中混凝土强度应用很低,一般混凝土只作重量而行使其职权,而元件在制造中是工厂化的,所以 Comrade Li Jin-sheng proposed the problem of fabricated hollow dam in “hydroelectric power generation”. In my opinion, it is a direction for improving gravity dam in the future. However, I have a bit of opinion on the elements and masonry proposed by Comrade Li. In my opinion, the unit components (referred to as components) with a square, the construction is relatively simple, so that the component itself in the gravity dam can meet the requirements of stress and strength, because the gravity dam concrete application is very low, the general weight of concrete only exercise its powers, The components in the manufacture of the factory, so
