摘要
在河道上无序采砂严重影响了堤防行洪安全。本文建立河道采砂对堤防安全影响模型,给出了采砂船相对于堤防安全距离的计算方法,初步估算了在无岸堤防的河道中采砂的安全距离。
The excessive extraction of sand in river course influences seriously the security of levee in flood period.The paper establishes a model of levee security influenced by extracting sand in river course,gives a computing method of safe dissidence between extraction sand ship and levee.The safe dissidence of extraction sand is estimated in river course without embankment.
