Abstract
This study investigates the deep foundation pit construction of the EPC-04 section at the Hangzhou Hezhuang-Yaqian section of National Highway G104,analyzing critical technologies for foundation pit support design,dewatering,and deformation monitoring.Addressing challenges including high groundwater levels,soft soil conditions,and the"One side is close to land,while the other side faces the water"imbalance,the research proposes a hybrid steel sheet pile and composite steel pipe pile support system.Combined with zoned well-point dewatering and reinjection measures,this approach ensures foundation pit stability and construction safety.The construction monitoring results indicate maximum horizontal displacement of 25.8 mm for both river-side and land-side support piles,maximum surface settlement of 4.2 mm,and axial force fluctuations within±8%-all within regulatory limits.关键词
