[0002] With the continuous advancement of infrastructure construction, the construction of pile-slab bridges on soft soil foundations is increasing. Soft soil foundations are characterized by high water content, large compressibility, and low bearing capacity. During construction, problems such as uneven settlement and soil displacement are likely to occur, which may cause various forms of damage to the pile-slab bridge structure.

[0003] Traditional evaluation methods may have limitations such as low accuracy, insufficient comprehensiveness, or difficulty in real-time monitoring, and cannot accurately grasp the specific damage conditions and their development and changes of the pile-slab bridge structure during soft foundation construction. As a result, the construction plan cannot be effectively adjusted in a timely manner, leading to immeasurable structural damage to the pile-slab bridge.

[0004] Therefore, in order to overcome the above defects, the present invention provides a method and system for evaluating the damage of a pile-slab bridge structure caused by soft foundation construction. Summary of the Invention

Finally, the structural damage characteristics of the pile-slab bridge are determined according to the mechanical property evolution laws and the material properties of each structural component, and an optimization scheme for the construction parameters is determined according to the structural damage characteristics. This facilitates the timely optimization of the construction parameters according to the optimization scheme, thereby reducing the structural damage of the pile-slab bridge caused by soft foundation construction.
