摘　　要：结合连申线航道整治工程,针对间隔木桩+竹篱生态护岸耐久性差的问题,提出间隔木桩+桑条秸秆拱新结构。该结构可充分发挥拱形结构良好的受力性能,解决竹篱结构单薄且受力不合理的问题;利用桐油和铜唑浸泡秸秆,提升了防腐性能。提出简便的秸秆拱制作方法,可集中规模生产,有效控制成本。试验段建设验证了此结构护岸应用的可行性和有效性:与连续木桩护岸相比,可大幅减少木桩的用量;与间隔木桩+竹篱护岸相比,可明显提升结构耐久性;同时,可实现部分秸秆的资源化利用。因此该结构经济性好,工程应用前景广阔。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.
