摘要
福建地区因地形地貌特殊,市政道路在建设时,常需通过"V"字形沟谷地带.为此,通常采用高填方路基方式进行处理.当填方路基厚度超过一定高度时,处理方式的选择直接影响工程建设的安全性及经济性.结合泉州一市政道路项目,考虑采用直立式加筋土挡墙来处理高填路基边坡,以节省工程造价,提高场地空间利用率并兼顾景观效果.通过技术分析研究,直立式加筋土挡墙支护方案具有较强的路基变形适应性,可有效保证路基边坡整体稳定性以及道路工后沉降要求,达到安全、经济、美观的工程效果.
Abstract
Due to the special topography and geomorphology in Fujian,municipal roads often need to pass through the"V"shaped gully zone during construction,which is usually treated by high fill subgrade.When the thickness of the fill subgrade exceeds a certain height,the selection of treatment methods directly affects the safety and economy of the engineering construction.In this paper,combined with a munici-pal road project in Quanzhou,the vertical reinforced soil retaining wall is considered to treat the high-fill roadbed slope,in order to save the construction cost,improve the utilization rate of site space and take into account the landscape effect.Through technical analysis and re-search,the support scheme of vertical reinforced soil retaining wall has strong deformation adaptability of the subgrade,which can effectively ensure the overall stability of the subgrade slope and the post-construction settlement requirements of the road,and finally achieve the en-gineering effect of safety,economy and aesthetics.
