Striking Out Towards Zero Settlement Control

This article describes how engineers in the Netherlands are using computer-controlled systems that measure the slightest ground or building movement as a result of tunneling. The alignment of the Hubertus tunnel in The Hague is a test of sorts for future large diameter tunneling projects under the heart of Amsterdam, where residents are extremely testy about the possibility of damaging historic buildings. The author describes the current project and the instrumentation installed for monitoring movement. It includes 74 Robotic Total Stations that take readings in continuous cycles, then compiles the data and delivers it to authorized computers. This in turn allows a rapid response to any alarms that are triggered. The Hubertus tunnel project is described in detail.
