Abstract
The extent of the influence zone affected by tunnelling depends on the amount of over-excavation and stress changes induced in the soil, normally represented as a value of volume loss. This paper combines upper and lower estimates of volume loss for different soil conditions and cover-to-diameter ratios in order to identify the zones around the tunnel influenced by tunnelling. These zones are combined with risk categories of damage of existing buildings in order to identify whether applying mitigating methods or taking additional control measures during tunnelling would be needed for a safe and damage-free tunnel construction. The influence of soil parameters on the influence zones is also investigated to identify their impact and quantity of the requirements for mitigating measures.
