Abstract:In Shenzhen area,geotechnical types are wide,geological conditions are changeful,and engineering environment is complex. These factors cause the excavation engineering support changeful and complex. The development history of excavation engineering in Shenzhen could be divided into five stages,i. e. such as primary experience,rapid development of many technologies,soil-nailing wall era,all kinds of technology rational application and deformation controlling. In the process of excavation engineering development,many new technologies are made or first used in Shenzhen,such as rotating drilling-mixing secant pile,rotating drilling secant pile,punching soil-cement secant pile,self-feed mixing anchor,high pressure jet expand head bolt,capsule type expansion body anchor,large diameter single pipe jet grouting pile,powder water pile,double-row pile,composited soil-nailing wall,inserts-anchor mixed supporting,etc.. These technologies represent the domestic advanced level. Seven typical excavation engineering examples such as Baoji Industrial Park Reconstruction etc.. have different and various style characteristics in the excavation engineering scale,depth,surrounding environment,construction process,supporting method,etc.,could stand for excavation engineering characteristics and the newest technology level in Shenzhen area.
