Ship collision has become one of the main reasons for the collapse of bridges across waterways, which has brought great challenges to the safety of bridges and the stability of transportation. The high pile cap structure is a common substructure form for inland bridges. It has good economy and construction convenience, but due to the poor anti-collision performance and low rigidity of the pile foundation, the installation of pile foundation anti-ship collision facilities is particularly important.
