Site Characteristic Curve and Risk Assessment for Buildings Around arge, Deep Excavations

摘要

During the design of large deep excavations on urban transit projects, both lateral and verticalrnground movements and their impact on adjacent structures need to be addressed. An excavation support systemrnshould be selected to limit the movements to acceptable levels. This study utilizes a hypothetical subwayrnstation excavation in medium dense sand to demonstrate how to develop site characteristic curves, which canrnbe incorporated into a risk analysis to determine the ground movement limits for controlling building damagernand modifying shoring design.
