文摘This paper reviews a number of engineering technologies and workmanships for addressing the challenging issues concerning possible landslides in large-scale slope reinforcement projects in China.It includes:(1) the multi-point anchored piles with a depth of 64 m in the Jietai Temple rehabilitation project,(2) soil nailing strengthened by driven pipe grouting technique covering an area of530 m × 100 m(length × height) in the Xiluodu hydropower project,(3) the cantilever piles extending vertically from the slope toe to stabilize a 300 m high slope at the Xiaowan hydropower station,(4) a new and simple workmanship for building a pile with cross-sectional area of 20 m × 5 m in the Hongjiadu hydropower station,and(5) comprehensive reinforcement scheme proposed for excavation of a 530 m high slope in Jinping I hydropower station.These new technologies can provide valuable experiences for reinforcement of high slopes of similar projects in China and other regions and countries with similar geological conditions.
