一种用于单桩基础水平承载性能试验的临时平台及方法
By driving vertical steel piles into the seabed to form a closed ring structure, combined with an equipment platform and ring beam reinforcement rods, the problem of insufficient support reaction force in the horizontal bearing capacity test of marine monopile foundations was solved. This achieved a test environment with high bearing capacity and high stiffness, facilitated the recovery of steel piles, and was economical.

AI Technical Summary
It is difficult to conduct horizontal bearing capacity tests on offshore monopile foundations, mainly because conventional temporary straight pile platforms have low bearing capacity and low stiffness, and cannot provide sufficient support reaction force.
Design a temporary platform comprising multiple vertical steel piles driven into the seabed to form a closed ring-shaped steel pile assembly, with a fixed equipment platform on top. The platform has pre-set openings to enclose the single pile foundation, with the inner side spaced apart from the single pile foundation. Ring beams and reinforcing rods enhance the connection strength, creating a test environment with high load-bearing capacity and high stiffness.
It effectively isolates the influence of wave flow, meets the support reaction requirements of the horizontal bearing capacity test of single pile foundation, and is easy to recycle and reuse steel piles, thus having strong economic efficiency and practicality.
