岭南高速公路路基填筑施工技术研究

Study on Roadbed Filling Construction Technology of Lingnan Expressway

岭南高速公路处于豫西丘陵山区,由于料源紧张及土地征用、运输等费用原因,在山区填筑路基往往只能就地取土或利用边坡、隧道开挖的风化岩石渣进行填筑,以节约成本和加快施工进度。为了保证路基的填筑质量,增强路基的整体稳定性,通过详细调查并结合土工试验,提出采用强风化岩进行路基填筑方案,并进行填筑工艺试验,取得了成功。

Lingnan Expressway is located in the hills and mountains in the west of Henan Province.It has to use the local soil or utilize the weathered rock slag from the excavation of the side slope and tunnel to fill and construct the roadbed in the mountains because of the short of material source and the costs of land acqurisation and transportation so as to save the cost and speed up the construction schedule.In order to guarantee the filling quality of roadbed and to strengthen the integral stabilization of roadbed,and through the detail investigation and combined with the soil engineering experiment,the article puts forward the scheme of using the strong weathered rock to fill and construct the roadbed and implements the filling construction technological experiment,which has succeeded.
