Abstract:
The foundation pit of the ship lock is the key to safety control during the construction period of the project. In depth analysis is conducted on the safety control issues during the construction period of the ship lock foundation pit. The focus is on the stability of the upstream and downstream cofferdams and foundation pit slopes of the ship lock,ensuring the safety of the project during construction. The study comprehensively considered multiple key factors such as terrain,hub engineering layout,navigation conditions,hydrogeological conditions,construction conditions,navigation impact during the construction period,land acquisition and demolition,and earthwork excavation. The stability of the upstream and downstream cofferdams and foundation pit slopes was analyzed in detail using the slice method. The research results provide a scientific basis for the safety control of the main foundation pit during the construction period of the Xiaoxiang hub ship lock reconstruction project,ensuring the smooth progress and construction safety of the project.
