In order to simplify the flexural tensile stress calculation method for the bottom of interlocking block pavement base under container corner loads,for the situation of container stacked in single or multiple columns,by introducing the interlocking block layer equivalent modulus concept,we simplified the interlocking block pavement to layered structure.On this basis,we analyzed the position variation of the maximum flexural tensile stress at the bottom of the base under container stacked in single or multiple columns,and given the regression formula of flexural tensile stress in the bottom of the base.Finally,the precision of the regression formula was analyzed with engineering examples.%为简化集装箱箱角荷载下联锁块铺面基层层底弯拉应力的计算,针对集装箱重箱按单列或多列方式堆放的情况,通过引入联锁块层等效模量概念,将联锁块铺面简化为层状结构.在此基础上,分析了单列或多列重箱荷载下基层层底最大弯拉应力的位置变化规律,给出了基层层底弯拉应力的回归计算公式,结合工程实例,验证了回归公式具有较高的回归精度.
