MONITORING BRIDGES OF THE NEW LEHRTER BAHNHOF IN BERLIN BY MEANS OF LONG-TERM STABLE SENSORS
Abstract
Two concrete bridges of the new Lehrter Bahnhof in Berlin have to be monitored with regard to their deformation performance during construction and later over several years. For this purpose sensors with excellent long-term stability are needed. The paper describes a new system for the measurement of settlements and elevations by means of laser-based optics and hydrostatic levelling, the application of fibre-optic strain sensors and conventional strain gauges, inclinometers and temperature sensors as well as model tests on pre-stressed concrete beams inside and outside the laboratory.
