Tatiana Richa, a geotechnical and data engineer with a Ph.D. at Terrasol, a subsidiary of the CTEC Group, presents Orbo, a collaborative web platform focused on soil investigation data. Terrasol is a geotechnical engineering firm specializing in the design of structures and the development of calculation software. 

In this video, discover how Orbo uses machine learning to predict ground surface deformations caused by tunnel excavation, leveraging data from construction sites such as the Grand Paris Express. The models, which are based on decision trees (random forests), can predict deformations up to 150 meters ahead of the tunneling face and provide near-instant results, thereby complementing traditional analytical and finite element methods. This solution offers engineers precise and responsive monitoring while reducing the time required for traditional calculations.
