软体柴排在浑河南天门险工治理工程中的应用

Application of Soft Mattress in Natianmen Risk Removal Regulation Engineering of Hun River

辽宁省浑河南天门险工治理工程根据防洪标准确定建筑物等级。综合水文、地质条件分析工程的现状和险工发展趋势,确定软体柴排为治理方案。依据设计原则确定排体材料、结构型式、排长设计、排体宽度设计、软体排压载设计、排体筋绳设计、水下排体的固定。软体柴排适应河床抗冲刷能力强,适应河床泥沙的变形能力,施工工艺简单。

The class of the construction for Natianmen risk removal regulation engineering in Hun River,Liaoning Province,is determined by flood control criteria.After analyzing hydrology,geological conditions,engineering status and hidden risk of the engineering comprehensively,soft mattress scheme is adopted for the risk removal regulation engineering.In terms of the design principles,mattress material,structure type,mattress length,mattress width design,soft mattress load design,mattress tendon rope design,underwater mattress fastening are conducted respectively.The soft mattress is characterized by the strong anti-scouring,resistance to deformation of the river course,and the construction technique is simple.
