Abstract
Under complex geological conditions,the stability and mechanical performance of geotechnical engineering support structure is very important for construction engineering.In order to study the applicability of common support structures in soft soil layer and high groundwater level,soil nailing wall,pile anchor support and shotcrete anchor support are selected as the research objects.Through field experiments and real-time monitoring,the deformation,displacement,stress and strain characteristics of each supporting structure are systematically analyzed.The results show that the displacement of soil nailing wall is the largest when the excavation depth increases,reaching 11.8 mm,showing a large deformation risk.The stress of pile anchor support increases the fastest,the maximum stress is 12 MPa,and the anti deformation ability is the strongest.The performance of shotcrete anchor support is moderate,which is suitable for medium depth foundation pit.关键词
