Monitoring measures

摘要

Currently, in the approximately 1200m excavated with EPB TBM monitoring, the behaviour of the neighbouring structures hasn't indicated any major distortions that may risk of stability or affect municipal facilities, Horcasitas reports.ICA brought in a permanent team in charge of instrumentation, and monitoring the software it has developed that allows the team to monitor everything in real time. For example, this instrumentation measures horizontal and vertical deformation, water pressure in the subsurface and topographic measurement in the surface and surrounding structures.
