Adaptive Planning of Grouting Measures in Tunnelling Using Artificial Intelligence

In the course of tunnel drives, pre-support measures can be necessary to waterproof or consolidate the surrounding ground. Since such measures can sometimes drastically slow the advance rate, their efficient planning is of great significance.

One frequently undertaken measure is grouting, which can be carried out flexibly with relatively simple machinery. Alongside this flexibility, continuous adaptation of the parameters as the work proceeds must also be possible. This may mean regular adaptation – both of drilling patterns and depths as well as grouting parameters, grout materials or stop...
