黄河下游河道整治续建工程坝垛型式设计

摘要

The groins will be more built at the lower part in the bends of the river training system in the lower Yellow River in the future. There are many disvantages to use the traditional earth-rock structure groins with the self-security and the construction investment. Through the analysis of the various existing types of groins and stacks in the Lower Yellow River,the improved groin structures were suggested based on the analysis of the structure stability and investment. The feasibility of the groins was also analyzed combining with the new water and sediment conditions and the need of engineering construction.%黄河下游控导工程的续建工程将主要修建在直线送流段，在这种前提下，传统土石结构丁坝在对洪水的适应性、自身的安全性以及投资的合理性等方面都遇到了新的问题。为更好地开展工程建设，通过对黄河下游各种已有坝垛型式的分析总结，在对结构稳定性、工程投资、工程运行安全等方面进行综合分析的基础上，对传统土石结构丁坝型式进行改进，并结合新的水沙条件及工程建设的需要，提出了适合下游控导工程建设的丁坝坝型。
