The Monitoring and Stability Analysis on Soil Nail Wall Supporting Excavation Engineering

Based on the test of the internal force on soil nail in soil nail wall supporting excavation engineering and the monitoring of excavation slope and the soil displacement near excavation slope,analyzes the relation of the internal force on soil nail and excavation depth,the distribution of the internal force on soil nail along the depth of soil nail in the different soil layer and the rule of excavation slope and the soil displacement near excavation slope. And it puts forward some guidance on the design and construction of soil nail wall.
