A Database of Numerical Simulation Parameters and Results for Anchor Cable Failure in Pile-Anchor Supported Excavations

This database is derived from an in-depth study on the failure mechanism of anchor cables in pile anchor support systems. This study established and validated a refined numerical model based on a deep foundation pit project, systematically exploring the impact of key parameters (position, quantity, timing) of anchor failure on the mechanical behavior of support structures and the stability of foundation pits. The core content of the database includes: Model validation data: includes on-site measured benchmark data used to validate the accuracy of numerical models. Parameterized scenario data: The system records the response data of support structures under different anchor failure scenarios (such as central anchor failure, edge anchor failure, multiple row continuous failure, and failure at different construction stages). Key indicator results: Detailed data on the full process changes of key indicators such as internal force, displacement, and redistribution of anchor cable axial force of supporting piles are provided.
