   Sammanfattning : The Incidence and Associated Geotechnical Issues of Swelling Clay in Stockholm  Viktoria Clarin & Anna Clark  Previous tunnel failures have shown that inadequate reinforcement in tunnels can lead to cave-ins, whereby swelling clay is one of several factors that can result in these damages. Swelling clay minerals possess the ability to absorb water molecules and cations leading to an increase in volume. LÄS MER
