Influence of Pit Excavation Supported by Soil-Nailing Wall on Adjacent Buried Pipelines

Abstract:

Underground pipelines affected by pit excavation are a practical problem often encountered in city foundation engineering. The characteristics of soil-nailing wall supporting include simplify, convenience, and low cost which make it widely adopted. Using MIDAS GTS for the integrated modeling, and the affecting factors are studied in four aspects, including excavation depth per step, pipelines’ depth, the distance between the edge of excavation and pipe, and the elastic modulus of surrounding soil. Some valuable conclusions for construction practice are drawn.
