临沂市小埠东橡胶坝坝基为第四系河流沉积的砂层,下游河床抗冲能力较低,由于河道采砂等原因,坝下游河道水位逐年下降,原设计消能防冲设施已不能满足消能需求。通过对小埠东橡胶坝下游进行水工模型试验研究,阐述了下泄的水流特点,确定出新的消能工的消能体型,较好地解决了相关工程问题,本设计对类似工程的设计有一定的借鉴作用。
臨沂市小埠東橡膠壩壩基為第四繫河流沉積的砂層,下遊河床抗遲能力較低,由于河道採砂等原因,壩下遊河道水位逐年下降,原設計消能防遲設施已不能滿足消能需求。通過對小埠東橡膠壩下遊進行水工模型試驗研究,闡述瞭下洩的水流特點,確定齣新的消能工的消能體型,較好地解決瞭相關工程問題,本設計對類似工程的設計有一定的藉鑒作用。

The Linyi -xiaobudong Rubber Dam is built on a soft foundation bed river. The ability of erosion - resisting of down stream is weak, which leads to the drop of river level year - by - year and finally current dissipation construction cannot adapt the demand. So the energy dissipation and erosion protection of down stream are major problems, which should be solved in the future project. Bis - energy dissipation is adopted in this project designing, and through the experimental study of hydraulic model, it revealed the rivers characteristic and solved the problem existed in the engineering.
