| Abstract: | The subgrade in Nanning-Kunming railway is very long and engineering conditions are complicated there. One of the key techniques is subgrade slope engineering in construction of the railway. Therefore,test and research on subgrade treatment of cataclastic expansive rock,retaining and protection of high cut slope in crushing and weak rock,and new retaining structure types of high embankment slope,such as piles-plate wall of prestressed anchor wire,reinforced earth retaining wall of new type straps,are conducted in combination with construction of the railway. Outstanding achievements of above research provide scientific foundation for smooth construction and safe transport of the railway. |
