淮河干流王家坝至临淮岗段位于淮河中游的前端,该段河型复杂,河道比降平缓。由于该河段河道行洪不畅,未达到设计泄洪能力,两岸行蓄洪区启用频繁、运用效果差,部分已建单项工程虽已建设完成,但尚不能充分发挥效益。鉴于此,本文通过分析王家坝至临淮岗河段存在的洪涝问题和河道特性,提出王家坝至临淮岗河段拟通过河道疏浚和和堤防加固等工程措施,打开淮河中游前端的进口,恢复淮河中游设计行洪能力。
Wangjiaba to Linhuaigang section of the mainstream of the Huaihe River is located at the front end of the middle reaches of the Huaihe River. The section of the river is complex and the river channel is more gentle than that of the lower reaches. Due to the poor flood control of the reach of the river and the failure to meet the designed flood discharge capacity, flood diversion areas across the Taiwan Strait are frequently used and ineffective in application. Some of the completed single projects have been completed but they have not been able to fully realize their benefits. In view of this, this paper analyzes the flood problems and the characteristics of the river from Wangjiaba to Linhuigang reach, proposes that the Wangjiaba to Linhuagang reach is to open the front of the middle reaches of the Huaihe River by engineering measures such as river dredging and embankment reinforcement, Resumption of flood control capacity of the middle reaches of the Huaihe River.
