Application of Shotcrete Bolt and Pile-anchor Retaining in a Deep Excavation Engineering

Abstract:

Because of the complicated geological conditions and the surrounding environment in the excavation site of Zhongnan Gardon Hotel, combined supporting method was adopted with shortcrete bolt and pile-anchor retaining. Safety for excavation construction, surrounding buildings and underground pipeline was ensured with lower cost and shorter construction period. The project set a successful case for similar engineering construction.
