Experimental study on pile-raft structure reinforcing deep silt foundation of transition section between bridge abutment and embankment

The pile raft structure of prestressed pipe-pile and reinforced concrete slab was applied in reinforcing the deep silt foundation of the high-speed railway transition section between bridge abutment and embankment.The field tests were performed,including lateral displacement and pore water pressure of the abutment foundation,settlement of the pile-raft structure and bending moment and lateral displacement of the abutment pile.Based on the measured data,the effects of driving pipe-piles on the ab...
