DOI: 10.1007/s12665-017-6425-z
Abstract: Abstract Tunnel excavation is a three-dimensional problem, especially in the zone close to the tunnel face. However, despite recent advances in computing resources, a full 3D numerical analysis is usually complex and requires important computational… read more here.

DOI: 10.1520/gtj20200009
Abstract: The assumption of treating the specimen volume as constant while experimentally determining the soil water retention curve (SWRC) of soils is valid only for nonplastic, granular soils. Fine-grained soils usually undergo significant volume change during… read more here.
