1 应用简况菏泽黄河位于黄河下游,相应黄堤桩号156+050～313+075,临黄堤长度157km。河道全长185km,现有险工、控导工程27处,坝、垛护岸681道,工程长度60km。现有堤防基础是1855年铜瓦厢决口改道后的冲积平原,土质多为沙土,不抗冲。还有历史上堵复堤防决口时的埽体形成的透水层和历次复堤施工质量等因素的影响,堤防安全存在着许多隐患,遇到洪水时容易出现渗水、管涌、滑坡等险情。以往人们为了战胜洪水,保护黄河的安全,大多采取加高堤防的方法。20世纪70年
1 Application Heze Yellow River is located in the lower reaches of the Yellow River, the corresponding embankment stake 156 +050 ~ 313 +075, Probation embankment length of 157km. The total length of the river is 185km. There are 27 dangerous workers, 27 pilot-controlled projects, and 681 dam and bank protection revetments. The project length is 60km. The foundation of the existing embankment is the alluvial plain after the diversion of copper wagons in 1855. The soil is mostly sandy and non-impact. There are also some historical reasons, such as the permeable layer formed by the body of embankment and the construction quality of previous embankments, which have many hidden dangers in embankment safety. In case of flooding, water seepage, piping and landslides are liable to occur. In the past, in order to defeat the flood and protect the safety of the Yellow River, most people took the method of raising the embankment. 70 years of the 20th century
