【摘要】 在桩承式加筋路堤多拱理论的基础上,推导了考虑加筋材料作用下的桩体荷载分担比的计算公式,同时给出了筋材的应力和变形计算公式。讨论了桩体荷载分担比和筋材力学性状随各种因素的变化规律.加筋材料在应变为6%的时候对提高桩承式加筋路堤的性能有很大的提高.更多还原

【Abstract】 The equations computing the vertical soil stress acted on pile caps and soils between piles are con- cluded using multi-arch theory.The equation coupled the geosynthetic-reinforcement is presented and the equations of calculating strain and stress of the geosynthetic-reinforcement are obtained.Finally,the factors af- fecting the ratio of load carried by pile caps and the tension in geosynthetic-reinforcement are discussed.The per- formance of piled geosynthentic-reniforced embankments is increased at the strain of 6% of geosynthetic-rein- forcement.更多还原
