Abstract

Based on field investigations of the geological structure, stratigraphic lithology, and groundwater depth of the excavation trench slopes at the Zhouqiao bridge site and Bianhe canal ruins, Kaifeng, together with slope deformation monitoring data, the stability of the trench slope was studied by numerical simulation using the FLAC3D model. The results show that under the self-weight condition, the maximum displacement of the trench wall is 3.87 cm and the factor of safety (FOS) is 1.18, indicating a basically stable state; under the combined self-weight and earthquake condition, the maximum displacement reaches 7.23 cm and the FOS is 0.943, indicating an unstable state. These findings provide a data reference for the selection and implementation of reinforcement and protection measures for the slopes of archaeological excavation trenches.
