Factors influencing the stress ratio are studied. The results show that the stress ratio is significantly affected by pile-soil modulus ratio and displacement ratio, while embankment height and embankment material less effect on it.
探讨了各主要影响因素与桩土应力比之间的关系,结果表明:桩土模量比和置换率是应力比的主要影响因素,路堤高度与路堤材料的影响次之;当路堤高度较小时,随着高度增加,桩土应力比提高明显;但当路堤高度增大到一定值时,桩土应力比基本不变;增大填料剪切模量可略微增大应力比。
