Use of Lateral Movements and Strut Loads in Inverse Analysis of Supported Excavations
Inverse analysis techniques can be used to calibrate finite element models of the construction of deep, supported excavations. If field observations are collected and transmitted to a host computer in real time, then these techniques allow one to update predictions of performance quickly enough to be of use to contractors and engineers responsible for the design and construction of the project. This paper presents procedures showing how both lateral movements measured by inclinometers, settlements and loads in support elements can be incorporated into such analyses. Results of simulations of synthetic excavations are presented to show how the sensitivity of the calibration varies as a function of the type of observation employed and how the sensitivity is increased when displacement and strut load data are used together as observations in the inverse analysis.
