【摘要】 低路堤公路不但能够节约耕地资源、减少土方量、降低工程造价,实现公路建设的可持续发展,而且能够提高公路的行车安全、使道路与周围环境和谐一致。文章以江北沿江高等级公路(南京段)工程为依托,结合弹性层状体系理论,利用BISAR程序研究了低路堤基底固化层对道路性能的影响,研究结果表明,基底固化层能够改善道路的使用性能,延长道路的使用寿命,减小车辆荷载作用引起的工后沉降。研究结果为今后低路堤的设计和施工提供了一定的依据。更多还原

【Abstract】 Low embankment road not only can save cultivated land,reduce earthwork,reduce project cost,but also can improve running safety,make road and environment all around consistent. Combined with north river this paper analyses the effect of basement solidified layer on road performance using BISAR program. The results indicate that the basement solidified layer can improve road property,prolong its usage lifetime,reduce post-construction settlement by traffic load,which will provide some basis for design and construction of low embankment in future.更多还原
