Method and device for pre-exploration during tunnel construction
摘要
<p>The method involves generating a seismic wave in the advancement region (2) of the tunnel (1) using a stimulation device (10), receiving reflected waves with a sensor arrangement and evaluating the seismic waves using a predefined propagation model. The sensor arrangement has a number of sensors distributed along the tunnel wall (3) for receiving surface waves running from the face (4)of the tunnel to the sensors. An independent claim is also included for an arrangement for preliminary surveying for tunnel construction.</p>
