摘要
将混凝土大头坝改造成实体重力坝并加高,尚未见工程先例.花溪大头坝已建成 41年,因供水要求的增加,需要将大坝改造成实体重力坝并加高.工程的实施要达到新老混凝土有机结合,形成同一个受力体,需要解决的技术问题很多.对一些关键的技术问题的研究结果和设计方案作简要介绍.
The modification of a massive-head buttress dam into a gravity dam with heightening of its body is unprecedented so far. Huaxi Massive-head Buttress Dam was built 41years ago. The increasing demand for more water supply makes it necessary to rebuild and heighten the dam. In the practice of the engineering, the old concrete and the fresh concrete are required to be combined together organically and to create a whole force bearing body, for which many technical problems are to be solved therein. So far as this project is concerned, a brief introduction to the design and the results of the research on some key problems is given hereinafter.
