Shoring-structure interaction in stabilization of excavation adjacent to historic buildings - A Case Study

摘要

This paper deals with the assumptions and analyses used to stabilize the excavation of holy Alavi courtyard located in Iraq. Numerical modeling of the problem is performed using PLAXIS software. Due to the connection of the main structure to the retaining system which consist of multi strand cable anchored concrete piles, the interaction between the structure inside the excavation and the retaining structure has been taken into account and its amounts has been investigated based on different scenarios for retaining system connection to the structure. Accuracy of the analysis is evaluated through comparing with actual displacements derived from monitoring of the excavation face during construction and useful conclusions are drawn.
