Analysis of factors influencing the safety and stability of excavation pit walls reinforced with soil nails in shallow tunnel construction

Abstract

The paper presents theoretical calculations and numerical simulations on the use of soil nails combined with shotcrete to reinforce and stabilize deep excavation slopes. The study focuses on analyzing the effects of soil nail length and certain geotechnical properties of the surrounding soil on the safety and stability of the excavation walls. Based on the analysis results, the paper provides evaluations and practical recommendations for the design and application of soil nails combined with shotcrete to reinforce and stabilize excavation slopes in shallow tunnel construction.
