Abstract:
Nanjing Foding Palace on Niushou Mountain is built in an existing mining pit. Considering tight construction schedule, high slope and large excavation workload, and complex geological conditions, reasonable slope ratio is designed according to the characteristics of rock and soil stratum, to protect the stability of side slope. Top-down side slope construction is adopted to successfully solve the difficulties in cross construction and effectively guarantee engineering quality and construction safety.
