| 摘 要： | 山区高填方路基应根据复杂多变的地形地貌及地质条件，形成针对性、综合性理念。通过广东省山区某在建高速公路，分析当前高填方路基主要填筑技术及工艺，提出综合利用填石路基、加筋土路基及高性能压路机补压等填筑方案和工艺，并进一步从稳定性及沉降方面研究对比各相关填筑方案。在四种方案中，“底部填石+中部加筋土路基+补强压实”方案，能满足山区高填方路基对稳定性和沉降量的要求。

| Abstract: | High fill subgrade in mountainous area should be designed with targeted and comprehensive concepts according to complex landform and geological conditions. Depending on a highway under construction in the mountainous area in Guangdong, the current main filling technology and process for high fill subgrade were analyzed, thus the comprehensive filling scheme including rock fill and reinforcement soil subgrade and then compaction by high performance road roller were put forward. In addition, the further comparison with various related filling schemes from the aspects of stability and settlement was carried out. Among the 4 schemes, the one having ＂ rockfill at the bottom ＋ reinforcement soil subgrade in the middle ＋ further compaction＂ could meet the requirement of stability and settlement of high fill subgrade in mountainous area. |
