东山水利枢纽拦河闸下游消力池遭受破坏，且下游河道河床下切、水位明显降低，严重影响工程的安全运行。为了解决工程存在的问题，拟在已破坏的消力池改造的基础上，在其下游修建二级消力池。根据拦河闸加固改造工程设计的闸址下游河道水位与流量关系资料，对拦河闸加固改造的下游两级消力池体型和消能特性进行分析和水力计算，提出了消力池的布置方案。研究提出的加固改造两级消力池方案经水力模型试验验证是合理的，其成果可供类似工程设计参考。

Owing to the damage of the downstream stilling basin of Dongshan water control project barrage ,the riverbed entrenchment ,and the significant degradation of the downstream river water-level ,the safe operation of the project is af-fected seriously .In order to solve these engineering problems ,on the basis of the transformation of the damaged stilling basin ,a secondary stilling basin was built at its downstream .Based on the data of the relationship between the down-stream river water-level of the barrage site and discharge capacity of the project design ,the configuration and energy dis-sipation characteristics of two stage stilling basins in the rebuilding design were analyzed and calculated hydrodynamical-ly ,moreover the arrangement scheme of the stilling basins was put forward .The rationality of the two stage stilling basin scheme was verified through hydraulic model tests .The study result will provide references for similar engineering de-signs .
