Parallel Seismic Testing Device for Foundation Piles Length

Parallel Seismic Testing Device for Foundation Piles Length The Parallel Seismic Testing method is to use a hammer (force bar) to strike the pile top surface (or the pile cap, pile cap and other superstructure connected with the pile top) in the vertical direction to generate the stress wave, and propagate downward along the pile body. when encountering the surrounding soil layer for transmission, sensors are placed in the holes drilled in advance beside the pile to receive
