摘要
辽宁省辽河辽中县下万子险工河道治理工程根据设计洪水标准,科学分析工程地质及水文地质及水文气象条件,确定石笼为治理方案。依据设计原则确定石笼网要求、砌石厚度、块石粒径、块石护坡稳定计算、工程施工方法。石笼防护的河岸险工整体性好、抗冲刷能力强,险工治理工程不受水流条件和施工工艺的限制。
In accordance with the design flood standard,as for the river course management project of the Xiawanzi dangerous section in Liaozhong County,Liaoning Province,the engineering geology,hydrological geology and hydrological weather were analyzed scientifically to decide the gabion as the management scheme.The demands on gabion box,thickness of stone-laying,diameter of rock block,calculation of crushed rock revetment stability and the method of project construction are determined based on the design principle.The dangerous section along the river bank protected with gabion is good of the globality and is strong in the ability to resist erosion,and the dangerous section management project is not limited by the flow velocity and construction technique.
