Application of Anchor Bolt Expanded Foundation Retaining Structure in Steep Rock Slope Section of Mountain Road |
| |
| Abstract: | Based on the retaining structure foundation design project of a secondary highway in west mountainous areas of Yunnan Province, the original design of balance weight retaining wall and anchor bolt expanded foundation retaining structure after optimization are compared.Results show that:anchor bolt expanded foundation retaining structure can reduce the work quantity and save investment, its form is beautiful, light and properly coordinated with surrounding landscape, and security can meet requirements of specification. |
