About the Seminar
Topic: Shield TBM - Ground Interaction: What Can We Learn From The Machine Data?
This lecture presents recent advances in understanding the complex interaction between shield TBMs and the ground through which they are tunneling. There are three main drivers for advancing this understand, namely (1) to make shield TBMs operate more efficiently; (2) to characterize the as-encountered ground; and (3) to eliminate unacceptable ground deformation. It is conceptually intuitive that the ground influences a TBM's behavior and that a sensed machine provides information about the ground conditions and its behavior. In concept then, rich data from the shield TBM can tell us a lot about the ground conditions. However, the interaction between shield TBMs and the ground is fairly complex and in many ways lacks mechanistic understanding. Recent research has used machine learning techniques to characterize the ground.
This presentation introduces this concept and examines the efficacy of ground characterization via exploitation of myriad forms of shield TBM data. At the same time, TBM's cause ground deformation. Estimating and controlling TBM-induced ground deformation is of paramount importance. The presentation examines the estimation of ground convergence and surface settlement via TBM data – associated with mechanistic modeling.
