The Application of Composite Soil Nail Wall in Foundation Pit Support Engineering
Effective support measures are required for large-scale commercial complex foundation pit engineering,and composite soil nail wall has been widely used due to its advantages.In order to study its application in foundation pit slope support,based on the commercial complex project in the south square area of Zibo Railway Station,this paper expounds the design scheme of foundation pit support based on many factors such as geological conditions,engineering environment and foundation pit excavation,analyzes the support principle of composite soil nail wall for each unit in detail,and uses Lizheng deep foundation pit software to check the stability of 11 units of the slope.The results show that the overall sliding stability coefficient of the 11 units of the slope is greater than 1.3 by using the composite soil nail wall support technology,which meets the design requirements.The application of this technology can ensure the safety of foundation pit excavation and has certain advantages in foundation pit support engineering.
