This means that the behaviour may be significantly different from an apparently similar deposited soil. Both the pattern of weathering development and this retained structure...

The mine is located in Chile, approximately 800 km north of Santiago, in a semidesert and mountainous area next...

... geology, i.e. bedrock, Quaternary deposits, groundwater, and also human activity. Geology is influenced by natural processes like volcanism, earthquakes, flooding, landslides, etc., and extensive human impact (cf. Selinus, 1996; National Atlas of Sweden, 1994). There is an increasing demand...

... on investigating the occurrence of liquefaction under the action of severe travelling fluid waves and its effects on sand bed deformation and particle transport. The characteristics of liquefaction and flow deformation are discussed on the basis of progressive-wave tests on loose deposits of fme-grained sand...

... dam and reservoir under all probable loading conditions. Any pre-existing landslides that might impinge on the foundation or abutments of a dam should be carefully investigated. If a landslide is recognized in a dam foundation or abutment, the landslide deposits commonly are avoided in siting the dam...

... ABSTRACT: Several significant design and construction issues related to geotechnical engineering of the Trans-Tokyo Bay Highway project are described. They are a) large scale improvement of existing soft clay deposits by in-situ cement mixing, controlling the strength of cement-mixed soft clay...

..., possibly tear faults trending N-E to S-W and steeply dipping, have been mapped on each side of the main ridge. The Alwar series and the post Delhi intrusives were covered by the Older Alluvium of Pleistocene age. These are generally interbedded, lenticular deposits of sandy silts with kankar (pebbles...

Connection of Artyemovsky Uplift with the contact zone of Dneprovsko-Donetsky Depression and Donetsky Ridge predetermined the depositional conditions in the Early Permian period when the Slavonic suite rocks were being formed...

... ABSTRACT: Loess soils cover approximately 10% of the world's landmass. Loess is an aeolian quaternary deposit of predominately silt size, which forms open metastable structures through various bonding agents. These agents include water, clay and carbonate and upon loading usually...

These port facilities need to be located along coastal zones with easy access to seas and oceans, and are nearly always located in areas underlain by deep soft marine deposits and include significant...

... earthquake activities. The landslide is an old rockslide of tremendous dimension. Its length is about 600m and width is about 1300 m. Due to lateral erosion of the Zeduo River, the frontal part of the landslide deposits failed frequently. On 15th June 1995, Kangding City hit by a strong rainstorm...

The dynamics of their change in time and space is directly dependent on the fracturing and the distribution of discontinuities in the geological environment. The most widespread type of similar influence during the underground mining of deposits...
