To solve the problem of poor durability of the alternate timber pile and bamboo fence structure，we propose a new structure of alternate timber pile and mulberry straw arch combining with the Lianshen channel regulation project. The good mechanical performance of the arch structure well solves the problem of fragility and stress imbalance of the bamboo fence structure，and soaking with tung oil and copper azole prevents corrosion of the mulberry straw. The easy method of making straw arch presented realizes mass production and cuts down the cost. which is standardized and possible for mass production and it greatly decreases cost. The construction of the test section verifies the feasibility and effectiveness of this new revetment structure：comparing with the continuous timber pile structure，it saves the timber pile consumption greatly；comparing with the alternate timber pile and bamboo fence structure，it improves the structure’s durability remarkably. Moreover，the straw resources can be partially utilized. So，this structure is economical and thus has a broad application prospect.
