港口靠船桩工作性状计算的双参数法

Fender piles calculation using biparametric method

港口靠船桩是承受重复性荷载或多循环荷载的一种横向承载桩。双参数法能较好地描述靠船桩 (单桩、群桩 )的桩土工作性状。用双参数法进行计算时 ,所给的地面条件必须由重复荷载或多循环荷载作用下实测出来。根据现场试桩资料 ,标定桩土参数 ,即k =mx1/n的指数l/n、桩土相对柔度系数α、桩土综合刚度EI等值 ,可以用来设计试桩附近局部地区同类条件下的其它长桩。对于没有进行试桩的某些工程 ,可以联合运用双参数法和p

Port fender piles bear repeated or multi circulation load. The biparametric method reflects the pile soil behavior of fender piles. Based on investigation and model tests, the biparametric method for fender piles calculation is discussed. The biparametric method can be used not only to calculate conventionally lateral loaded piles, but also to calculate multi circulation laterally loaded fender piles (pile and pile groups). The key of the biparametric method is the work parameter of piles construction. For piles not tested, both the biparametric method and p y curve method may be used jointly in the calculation.
