| 摘 要： | 针对西藏某公路的加宽改造,提出了5种新旧路基加宽拼接方案.按这5种方案,共修筑了3段试验路.对试验路的设计原则、施工要求和工艺进行了讨论.通过试验数据,对各种拼接方案的效果进行了比较分析.结果表明,用5层双向土工格栅自路基顶面向下,以层间距30 cm的加筋方式加强新旧路基间的结合是较好的路基加宽拼接方案. |

| Abstract: | Three sections of experimental embankment were constructed in a widening highway project in Tibet,including 5connecting patterns between the widened and the old part subgrade.The design principles,the construction specifications and procedures are discussed.Based on the test data,a comparison among the efficient of each connecting pattern is presented,according to which the method is suggested that of placing 5biaxial geogrid layers placed horizontally in the widened part of embankment with a spacing of 30cm. |
