Abstract
A method for detecting a deflection basin based on a deformation velocity of a pavement under a rolling load is provided. The method includes: obtaining vertical deformation velocities of the pavement at respective measurement timings corresponding to respective target locations in a target deflection basin during the load movement; obtaining durations for respective response time intervals corresponding to the respective target locations based on the respective measurement timings, the vertical deformation velocities of the pavement at the respective measurement timings and a knowledge base model; obtaining representative vertical deformation velocities of the pavement based on the vertical deformation velocities of the pavement, the durations for respective response time intervals, and the knowledge base model for the vertical deformation velocities of the pavement; and obtaining detection results of the target deflection basin based on the representative vertical deformation velocities of the pavement and the durations for respective response time intervals.
