<p>TBM tunneling is an ever-increasing prospect for underground construction, and with each new tunnel bored there are unknown elements. When boring through the earth, even extensive Geotechnical Baseline Reports can miss fault lines, water inflows, squeezing ...

<p>The flow of bentonite and grout around a TBM influences the settlement trough that is created during TBM tunneling. Not taking into account this flow, leads to a calculated settlement trough that is too deep. Two calculation methods have been developed: ...

<p>Natural gases are a potential hazard in construction of underground excavations. Encountering with gases usually result in costly delays. Gases occur in a wide variety of geological conditions, so predict the occurrence of potentially hazardous concentrations ...
