Abstract
In this tunnel, uplift of the pavement surface was confirmed after service was started. After that, field surveys, onsite monitoring and laboratory tests were carried out, and one of the causes of the deformation was pointed out: in addition to progressive deterioration of the ground due to tunnel drilling, the influence of groundwater infiltration from the around tunnel and absorption swelling due to groundwater supply.
