With a suggested displacement model , this dissertation takes the interaction of soil and piles into consideration and derives an analytical - function of compressive deformation of stabilized layer of composite foundation under embankment . analytical - functions are also derived of frictional resistance between pile and soil and of the pile - soil stress ratio 本文在假設的位移模式下,考慮樁土相互作用,通過力學推導,得到了路堤荷載下復合地基樁側摩阻力、加固區(qū)樁間土壓縮量和樁土應力比的解析表達式。
