本文作者根据一些工程实践经验和资料,对混凝土坝温度控制问题提出了与现用的理论、观点不同的认识和看法,这就是:基础贯穿裂缝不一定是最危险的裂缝;大体积混凝土开裂的主要原因是内外温差;防裂措施应以保温为主、降温为辅等。这些问题关系比较重大,也是水电建设及有关部门工程设计、施工人员十分关心的问题,欢迎读者就此展开讨论,以推动这一技术向更合理、更全面的方向发展。
Based on some practical engineering experience and data, the author puts forward some different opinions and opinions on the temperature control of concrete dams. This is that the foundation through cracks is not necessarily the most dangerous one; the cracking of mass concrete The main reason is the internal and external temperature difference; crack prevention measures should be based insulation, cooling and other auxiliary. These issues are of great importance and are also issues of great concern to the construction design and construction workers of hydropower and related departments. The readers are welcome to start discussions on this issue in order to promote this technology to a more rational and comprehensive direction.
