Abstract

Abstract: This study adopts the local and global sensitivity analyses to study the influence of the soil-tunnel-building system characters (e.g. soil properties, building's stiffness and position, tunnel volume-loss and embedment depth, soil-building interface properties) on the settlement and tilt of building. To properly update the design parameters during tunnel construction, a field sensitivity analysis is proposed to find the optimal position of the sensors in a priori to increase the quality of measurements (less uncertainty) which leads to efficient identification of the soil parameters from the measurements. The validity of this methodology is justified by applying it to a case study.
