Influence of Compaction Effect of Jacked Pile Group on Adjacent Subway Tunnel and Prevention and Control Measures
The jacking method construction of prefabricated pipe piles is widely used in urban construction due to its efficient working method,no noise and no vibration in construction,reliable quality and high economic benefits.However,the compaction effect problem in the process of pile loading often causes hazards such as soil uplift and horizontal displacement,as well as damage to the surrounding auxiliary structures.This paper takes a project in Guangzhou as an example to analyze the adverse effects of compaction effect of jacked pipe piles on adjacent subway tunnels and the prevention and control measures,so as to provide reference for similar engineering projects.
