土工充泥袋抛坝促淤试验研究与实践

Experimental study and practice of constructing diskes by using woven geotextile bags

作者对土工充泥袋代替块石作为建筑材料,在水流作用下袋体的保沙性能和充泥袋的稳定性能等关键问题开展了一系列室内外试验研究,并提出了相应的解决措施。根据土工充泥袋稳定要求而研制的新型袋体"沙垫"现已在工程实践中广泛应用。

The Authors investigated a new type of dikebuilding materials and method in the Qiantang River Estuary,which is characterized with strong tidal bore and high current velocity.A series of tests indoor and insitu were carried out about the sand permeability and stability of the woven geotextile bags under the action of current flow.The traditional method of riprap was replaced.As a result,the new type of method was proved and can be applied widely in practice.
