| 摘 要： | 岩堆路基是山区公路建设中遇到的特殊路基形式。根据云南水(富)—麻(柳湾)高速公路岩堆路基条件,通过离心模型试验研究了不同土石组成、不同容重、不同厚度的岩堆路基沉降变化规律和影响因素,提出了用片石换填、加筋土换填、稳定土换填减小岩堆路基沉降的措施;测试了三种换填处治措施减小岩堆路基沉降的效果,得出了稳定土换填和片石换填对减小岩堆沉降效果较好的结论。研究成果对岩堆路基沉降稳定性分析和减小沉降的合理处治措施有重要参考价值。

| Abstract: | The cliff debris subgrade is a special type of subgrade in mountainous highway construction.Based on the cliff debris subgrade conditions of Shui-ma Highway(from Shuifu to Maliu Bay) in Yunna Province,the rule and the influence factors of sedimentation change of rock subgrade settlement which is of different ratio of soil and rock,of different density,and of different thickness are studied by centrifuge model test.According to the centrifuge model test results,three methods of reducing cliff debris subgrade... |
