摘要
永定新河是天津市防洪的北部防线。由于受海相来沙淤积 ,河道行洪能力大幅度下降。针对永定新河治理工程设计中涉及到的河道淤积治理方案、闸位比选、防潮闸结构型式及施工方法、闸下减淤清淤措施等诸多问题进行了分析和研究 。
Yongdingxin River is the northern protection route on flood control in Tianjin.The river channel flood discharge capacity is tremendously decreased because of the marine sedimentary deposit.Analysis and study has been carried out in this paper on several problems such as the river channel sedimentation harnessing scheme,the comparison and selection of gate locations,the structural type and construction method of the tidal gate and the sedimentation releasing and de silting measures applied to gate surroundings,etc.\{related\} to engineering design of the Yongdingxin River harnessing works,and the corresponding solutions and proposals have also been put forward.
