摘要

摘要: 目前规范中管桩的水平承载设计仍参考普通灌注桩,造成设计偏于保守。为了揭示管桩双桩在水平荷载下的承载机理及群桩效率综合系数的安全储备值,结合黄河冲积平原某工程进行了现场试验。结果表明：管桩双桩承载力试验值大于规范计算结果,得到的群桩效率系数是规范法计算值的1.20~1.35倍。研究成果可为今后同类地区水平承载管桩的设计工作提供参考依据。

Abstract: During the past decades, the design of horizontal bearing pipe piles has still referred to that of bored piles, as a result, the conservative design has been found frequently. In order to get the bearing mechanism and pile group effect coefficient of double pipe piles under horizontal load, field tests are carried out. The test results show that the bearing capacity of double piles are larger than the calculated results from the China's Technical Code for Building Pile Foundations. The Coefficients of pile group effect of model tests are approximately 1.20 to 1.35 times than the calculated results from the Code. The research results are useful for the design of pipe piles under horizontal load in the same areas.
