摘要
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。
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.
