一、引言像混凝土坝这样的大型建筑物,必须考虑其安全性,因为他们在运行中失事可能会导致巨大的灾难,即使是在产生危险局面前可以通过修理来解决的小事故也能造成相当大的直接或间接损失。因此,这种建筑物运行中的安全控制是必要的,而且为了改进设计标准和建立 I. INTRODUCTION Large buildings such as concrete dams must consider their safety because their failure during operation can lead to a catastrophic disaster and even small accidents that can be solved by repairs before a dangerous situation can be caused Large direct or indirect loss. Therefore, this kind of safety control in building operation is necessary, and in order to improve the design standards and establish
