Comprehensive Application of Deep Foundation Pit Supporting Technology in Rich Water Area
The comprehensive application of deep foundation pit support technology in water-rich area is introduced in detail based on foundation pit support engineering in an urban area.Based on the analysis of the project situation and geological conditions,the paper proposes the use of"slope protection pile+prestressed anchor"support system,"composite soil nailing wall"support system,"soil nailing wall"support system and"slope hanging net shotcrete anchor"support system,and puts forward the construction key points and requirements of foundation pit support.The monitoring results show that the maximum vertical deformation occurs in the 4b-4b and 4c-4b support sections on the northeast side of the foundation pit.
