ABSTRACT
ABSTRACT: Aimed at the geological condition and surrounding environment of Huitongtianxia Building’s deep foundation excavation, two supporting plans, pile-anchor protection and composite soil nailing walls, were separately adopted to meet the needs of different excavation regions. Based on analyzing the supervising results of horizontal displacement of foundation excavation’s pile top, composite soil nailing walls’ slope top and pile-anchor protection’s wale, and the supervising results of the building’s sedimentation, the pile-anchor protection structure and composite soil nailing wall effectively guaranteed the successful construction of foundation excavation and the security of surrounding buildings.
