摘要: 在相同地质条件下,对同一种设计桩型,分别采用慢速维持荷载法和单向多循环加卸荷载法两种试验方法,得出静载试验Q~y、y~lgt曲线及H~t~Y0、H~△Y0/△H曲线,并结合数据统计分析,初步得出两种试验方法的单桩水平荷载的关系。

Abstract: Two different loading procedures in the horizontal pile loading tests have been performed on the same pile type in the same subsurface condition. These two methods are: Maintained loading method and monotonic cyclic loading method. The different Q~y, y~lgt and H~t~Y0, H~ΔY0/ΔH curves are obtained under both loading procedures.
