... ABSTRACT: Landslide and rockfall disasters frequently occur on road systems. Therefore, analyzing the disaster rapidly and deciding on the remediation method, is the key to reducing the loss. We have developed a ‘Highway slope disaster information collection, integration, simulation...

... of OPA in-situ. For the interpretation of radial pressures, the mechanical properties of the annular gap grout were explored and the impact of thermal strains on measured radial stresses was investigated with numerical simulations. Here we discuss key results obtained from the new Belchen tunnel that can...

These models provide cross-sections for slope analysis and can simulate future mining progress and water level...

..., potentially disrupting transportation and the delivery of essential services. While there were notable publications in the late 1920s (Taber, 1929) that contributed to understanding the phenomenon of frost heave in soils, modeling efforts did not begin until later. A reliable numerical simulation model...
