CSi - a joint industry project into CPTUs in silty soils
(Chapter, 2022) -
Dam Tunsbergdalsvatn. A dam subjected to waves generated by avalanches, and to extreme floods from a glacier lake
(Chapter, 1976)The construction of Leirdøla power plant was started in 1975 and will be completed in 1978. The owner is the Norwegian Water Resources and Electricity Board. The power plant is situated in Western Norway, close to ... -
Data-Fusion Based Vulnerability Analysis of Shield Driven Tunnel Suffering from Extreme Soil Surcharging
(Chapter, 2019)A new data fusion approach is presented for evaluating the vulnerability curves utilizing multi-source monitoring information. A Bayesian network with continuous variables for a shield driven tunnel involving the loading ... -
Decision-Based Approach to Account for Uncertainty in Estimating the Overtopping Hazard to Manage Risk for Dams
(Chapter, 2019)This paper describes and demonstrates an approach to improve the management of risks from small-probability events that can lead to large consequences. It applies a decision-based theory to account for limited information ... -
Dense avalanche numerical modeling interaction between avalanche and structures
(NGI Publication;203, Chapter, 1998)Applications of the Saint Venant equations were extended to rapid gravity flows of geophysical fluid with a non-newtonian behavior such as snow avalanches. This paper presents a numerical and physical approach for snow ... -
Design Aspects of Suction Caissons for Offshore Wind Turbine Foundations
(Chapter, 2017)This paper provides an introduction to the geotechnical design of suction caisson foundations for Offshore Wind Turbine (OWT) foundations. It summarizes the experience gained in a number of projects from across the world ... -
Design criteria for cylindrical masts exposed to snow creep forces.
(NGI Publication;203, Chapter, 1998)Based on 23 years of measurements of snow creep forces on cylindrical masts, a relation between the pressure and snow parameters as snow depth, density and temperature, has been established. The long observation period has ... -
Design of snow avalanche deflecting dams
(Chapter, 2000)Extensive effort has been put into improved understanding of avalanche deflection over the last two years. This paper discusses construction of deflecting dams in steep terrain, and gives an in-depth description of the ... -
Determinación de la velocidad de avalanchas de nieve mediante datos sísmicos
(Chapter, 2006)Seismic instrumentation has proved to be a reliable tool for snow avalanche detection. In this approach, besides the detection skills of our system we pretend to go one step further. We aim to infer a physical parameter ... -
Development of an enhanced CPT system for Dogger Bank
(Chapter, 2022)An enhanced seafloor CPT system has been developed to support completion of the soil investigation campaign for Dogger Bank. This enhanced system has a demonstrable and significant performance increase over standard seafloor ... -
The differentiation of thaws in connection with slushflow occurrences.
(NGI Publication;203, Chapter, 1998)Classification of meteorological conditions accompanying slushflow occurrences is attempted. Days with mean daily air temperature above O°C have been chosen for the analysis. Each day has been described with a set of ... -
The diversities of large slushflows illustrated by selected cases.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2010)Rapid mass movement of water-saturated snow, usually known as slushflow or slush avalanche, is a major natural hazard in Norway. The destructive forces are larger than those observed from other snow related mass flows of ... -
Drifting snow in complex terrain. Comparison of measured snow distribution and simulated wind field.
(Chapter, 2000)Snowdrift in complex terrain can cause significant problems for maintenance of road and railway systems during winter and is a major factor for snow avalanche releases. The location of accumulation and erosion areas is ... -
DUE avalRS: Remote-Sensing Derived Avalanche Inventory Data for Decision Support and Hind-Cast after Avalanche Events
(Chapter, 2010)Each year, snow avalanches hit populated areas and parts of the transport network in the Norwegian mountain regions, leading to loss of lives and the damaging of buildings and infrastructure. We present the results of a ... -
Dynamics of two-layer slushflows
(NGI Publication;203, Chapter, 1998)A new mathematical model of slushflow dynamics is developed. A slushflow is treated as a two-layer flow. The lower layer consists of pure liquid phase (water) and the upper layer is a floating water saturated snow (slush). ... -
Dynamique et modélisation des avalanches
(Chapter, 2010)This chapter summarizes observations and experimental findings on the dynamics of snow avalanches that are important to understand when developing or applying numerical models for the calculation of runout distances, ... -
Earthquake Geotechnics in Offshore Engineering
(Chapter, 2018)This paper presents a number of geotechnical issues encountered in earthquake design of offshore structures and subsea facilities. Parallel with construction of traditional structures such as jackets and gravity-based ... -
Effect of cone penetrometer type on CPTU results at a soft clay test site in Norway
(Chapter, 2018)Seven different cone penetrometers from 5 manufacturers have been used in a comparative testing program at the Norwegian GeoTest site (NGTS) on soft clay in Onsøy, Norway. Tests with all cone types give very repeatable ...
