摘要

The corrosion problem of steel pile foundations in marine environments poses serious challenges to structural safety and engineering economics. The corrosion behavior of Q235 steel in marine geotechnical environments is analyzed through laboratory simulations and field investigations. A multifunctional simulated ocean test system is used, taking into account factors such as seawater circulation, temperature control, wind blowing, and sunlight. The results indicated that the friction coefficient of residual soil and weathered rock significantly increased under different degrees of corrosion, while the changes in marine clay and silty clay were not significant. The load–displacement curve of the axial tension component showed that the increased corrosion reduced maximum load, and the magnitude of load reduction increased with the increase of displacement after exceeding the maximum load point. In the analysis of vertical load–displacement relationship, the increased corrosion degree from 0 to 1.6 mm resulted in a decrease in vertical load from approximately 8400 to 7350 kN. The reduction in surface roughness and wall thickness had a particularly significant impact on the bearing capacity. The research provides a scientific basis for the corrosion assessment and management of steel pile foundations in marine environments, which helps to improve the safety and economy of structures and has important guiding value for engineering design, construction, and maintenance.
