小角度缠绕复合材料护岸管桩抗弯性能试验与设计
Test and design of bending performance of small-angle winding composite revetment pipe piles
摘要
Abstract
This paper proposes a new composite revetment pipe pile.The revetment pipe pile is made of com-posite winding pipe prepared by the fiber winding process.Through the four-point bending test,the failure mode and load-displacement relationship of the specimen were obtained,and the influence of winding angle±55°,±15° and whether concrete was poured on the bending performance of the revetment pipe pile was analyzed.The results show that the reduction of the fiber winding angle from 55° to 15° and the pouring of concrete can greatly improve the stiffness and bending bearing capacity of the composite revetment pipe pile.Then,the calculation formula of the embedded end depth of composite revetment pipe piles is derived on this basis,and the design process and applica-tion suggestions of revetment pipe piles are given.This provides a reference for the later application of composite re-vetment pipe piles in revetment projects.关键词
