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