Study on Engineering Behavior of Non-Embedded Pile-Board Structure Crossing Over-Shallow-Embedded Metro

Abstract:

It’s the first application of NEPBS crossing over-shallow-embedded metro in deep soft ground on new Shanghai-Hangzhou passenger dedicated railway (SHPDR) in China. It’s necessary to study the engineering behavior of NEPBS in complex geology field. Long-term observation systems were installed at the typical test sections of SHPDR; Combined with theoretical analysis model, the mechanical properties and deformation laws were analyzed and tested. Measurement results show that the test reinforcement stresses of loading plates and supporting beams are small; the test bending moments agree well with the theoretical bending moments, which are far less than the resistance bending moments; the piles improved the mechanical properties of deep soft ground, so the plate-soil contact stresses are small, the maximum value is 132 kPa; 45 days after the train operation, the post-construction settlement is 1.86 mm; the settlements of individual test points are not yet stable, but they tend toward stability, which can meet the requirements of settlement control of SHPDR.
