Support technology of deep foundation bracing and quality control

Abstract

Ruibai Times Project lies in the central city area of Jinzhou District, Dalian. With the abundant underwater, the geological condition is quite complex. Underground public transportation, old brick-concrete buildings and converting station are all around the construction site. The deep foundation excavation exceeds 17m. The support design adopts a combination of pile anchor system and internal support, which better solves the problems concerning safety, construction period, and cost. The quality is controlled during the construction process, and the monitoring results show that the support method is safe and reliable.
