摘　　要：通过对大量模型试验结果的分析,提出了简便合理的水平荷载作用下单桩的计算方法。该方法将常用m法中单一m值与位移建立指数关系,并由bm及k两参数来描述。将这一关系引入常用单桩m法计算中,则计算结果可考虑单桩非线性响应的影响。Based on a series of model tests of piles,a new method for calculating single pile under lateral loading was presented.The popular constant 'm'value was related with pile head deflection by power function,and this relationship was described by two factors:b m and k.With this relation introduced into the method'm',the calculation results can consider the influence of the non-linear response of the single pile.
