Landslides Susceptibility of Chittagong City, Bangladesh and Development of Landslides Early Warning System
(Chapter, 2018)Chittagong, the second largest city of Bangladesh, is mostly developed in the hilly areas. Hills are mostly covered with loose and weathered tertiary sedimentary rocks susceptible to landslides. Generally, during heavy ... -
Large scale driving of concrete piles in stiff to very stiff clay
(Chapter, 2016)BAMA Gruppen AS have constructed a new 44 000 m2 warehouse, office and distribution centre in Groruddalen in northern parts of Oslo, Norway. Norwegian Geotechnical Institute (NGI) were employed as geotechnical consultants, ... -
Laws of friction in snow mechanics
(Chapter, 1976)Laws of sliding and friction are of primary importance in the determination of pre-fracture conditions for slab avalanches as well as for practical considerations such as determining snow pressure loads on constructions ... -
Lessons learned from the 2015 Soerkjosen shoreline landslide in Norway
(Chapter, 2017)Soft and partly sensitive clays along the fjords of northern Norway pose a challenge for infrastructure. Learning from failures is essential in providing guidelines for future geotechnical work in such areas. A shoreline ... -
Long-term forecasting of changes of snowiness and avalanche activity in the world due to global warming
(NGI Publication;203, Chapter, 1998)The technique of definition of depth of the snow cover, number of days with the snow cover, number of days with intensive snowfalls, duration of avalanche prone period by the standard meteorological data (precipitation and ... -
Longyearbyen, Svalbard - Vulnerability and risk management of an arctic settlement under changing climate - a challenge to authorities and experts
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2016)Longyearbyen, the administrative centre of the Svalbard archipelago, is facing most types of natural hazards under a changing Arctic climate. The catastrophic avalanche in December 2015 led NGI to review our professional ... -
Los suelos marinos de la Sonda de Campeche y Litoral Tabasco, Golfo de México
(Chapter, 2019)En la Sonda de Campeche y Litoral Tabasco, Golfo de México, se han realizado más de mil sondeos geotécnicos y dos mil estudios geofísicos. Los sondeos tienen diversos objetivos, tales como: diseño de cimentaciones para ... -
Mathematical modeling of dense avalanches
(NGI Publication;203, Chapter, 1998)The paper presents a brief overview of mathematical models for dense avalanches that were developed by researchers of Moscow State University. Examples of calculations for real avalanches in Caucasus and Khibiny Mountains ... -
The meteorological condition for larger avalanches at Senjojiki Bowl in Japanese Central Alps
(NGI Publication;203, Chapter, 1998)The Senjojiki Bowl has a typical avalanche terrain consisting of8 avalanche tracks. During the last 25 years 16 alpinists and ropeway workers in total have been killed by avalanches. Since no reliable avalanche warning is ... -
Modelling the 1929 Grand Banks slump and landslide tsunami
(Chapter, 2018)On 18 November 1929, an Mw 7.2 earthquake occurred south of Newfoundland, displacing >100 km3 of sediment volume that evolved into a turbidity current. The resulting tsunami was recorded across the Atlantic and caused ... -
Models for powder snow avalanches : comparison of two approaches
(NGI Publication;203, Chapter, 1998)Two models are considered in this paper: one was proposed in Kulikovskiy and Sveshnikova (1977) and is referred here as KS-model, the second was described in Beghin and Brugnot (1983), and is referred here as BB-mode!. ... -
Monotonic and dilatory excess pore water dissipations in silt following CPTU at variable penetration rate
(Chapter, 2016)The relationship between cone penetration rate and pore pressure decay is investigated through dissipation tests following penetration at different rates. Field tests and model scale tests in the laboratory are performed. ... -
A new concept for avalanche warning in Switzerland
(NGI Publication;203, Chapter, 1998)During the past 60 years the Swiss Federal Institut for Snow and Avalanche Research (SLF), which is in charge of the avalanche warning in Switzerland issued national avalanche bulletins three to four times a week at around ... -
New CPT methods for evaluation of the axial capacity of driven piles
(Chapter, 2022)High costs associated with offshore foundation installations have provided strong impetus to the offshore energy sector in the search for more reliable design methods. This paper provides a summary of an Industry sponsored ... -
