The main focus of my reserach is data collection and analysis for developing predictive models that can be applied in different areas of interest:
Prediction of ground surface movements due to mechanized tunneling, using mathematical modeling.
Building a database with information on various tunneling projects around the word. Prediction of TBM advancement rates and development of an algorithm to predict the ground surface movements using information about the soil and the TBM operational parameters.
Numerical modeling of soil behavior and response to tunneling.
Calibration of advanced soil models, such as MIT-S1, for describing the soil behavior of the different units of London Clay and its response to tunneling. Applications on Crossrail, Jubillee-Line Extension and Heathrow Express tunnel cases.
Numerical modeling and prediction of ground lateral movements in braced excavations.
Development of a method for accurate prediction of the lateral movements of a corner-braced secant pile wall with simple commercial 2D FE models and soil properties from basic in-situ tests.
