Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
Во время прошлых землетрясений было выяснено, что колебания грунта на мягких участках почвы в целом больше, чем близлежащих горных пород, в зависимости от местных грунтовых условий (например, Сид (Seed) и Идрис (Idriss), 1968). Такие усиления реакции грунта симулировались с помощью нескольких компьютерных программ, в которых принимались упрощенные грунтовые условия, такие, как горизонтальные слои грунта бесконечной протяженности.
Engineering geology provides a vital link between the established, traditional, and relevant disciplines that link its identity and name; that is, “engineering” and “geology.” More recently, a variety of other fields of study are viewed as synonymous with engineering geology including but not limited to geotechnics, geological engineering, environmental engineering, environmental geology, applied geology, and so on.
The field of hydrological science deals with the occurrence, distribution, movement, and properties of water on the earth. The science of hydrology holds a unique and central place in the field of earth system science, intimately linked with other water-related disciplines such as meteorology, climatology, geomorphology, hydrogeology, and ecology. Beyond basic scientific interest, water quantity and water quality have become two of the most pressing environmental issues of our time.
More than ever before, a compelling need exists for an encyclopedic resource about soil the rich mix of mineral particles, organic matter, gases, and soluble compounds that foster both plant and animal growth. Civilization depends more on the soil as human populations continue to grow and increasing demands are placed upon available resources.
The Encyclopedia of Soils in the Environmentis a comprehensive and integrated consideration of a topic of vital importance to human societies in the past, present, and future. This important work encompasses the present knowledge of the world's variegated soils, their origins, properties, classification, and roles in the biosphere. A team of outstanding, international contributors has written over 250 entries that cover a broad range of issues facing today's soil scientists, ecologists, and environmental scientists.
This four-volume set features thorough articles that survey specific aspects of soil biology, ecology, chemistry and physics. Rounding out the encyclopedia's excellent coverage, contributions cover cross-disciplinary subjects, such as the history of soil utilization for agricultural and engineering purposes and soils in relation to the remediation of pollution and the mitigation of global climate change.
This entry explains the use of emergy analysis to evaluate systems and compare resource use, environmental loading, and sustainability. This method allows the free contributions of the environment to be compared directly with the purchased inputs from the economy. Results summarized from agriculture and forestry systems indicate that extensive amounts of indirect energy were dissipated to yield agricultural and forest products and that timber typically requires less indirect energy than crops.
Программный комплекс «EngGeo» предназначен для работы с данными инженерно-геологических изысканий. Основными возможностями комплекса являются:
• хранение данных по бурению скважин, по лабораторным пробам грунтов и вод, по полевым испытаниям; • расчет физико-механических и химических характеристик грунтов и вод и их статистическая обработка; • создание текстовых отчетов по испытаниям и проходке выработок; • построение чертежей колонок скважин и разрезов.
As noted in the Preface to the first edition, engineering geology can be defined as the application of Geology to engineering practice. In other words, it is concerned with those geological factors that influence the location, design, construction and maintenance of engineering works. Accordingly, it draws on a number of geological disciplines such as geomorphology, structural geology, sedimentology, petrology and stratigraphy. In addition, engineering geology involves hydrogeology and some understanding of rock and soil mechanics.
Similar to the first edition, this edition too is written for undergraduate and post-graduate students of engineering geology. It is hoped that this will also be of value to those involved in the profession, especially at the earlier stages of their careers. However, it is aimed at not just engineering geologists but also at those in civil and mining engineering, water engineering, quarrying and, to a lesser extent, architecture, planning, surveying and building. In other words, those who deal with the ground should know something about it.
This textbook aims to impart comprehensive knowledge of engineering geology to the undergraduate students of civil engineering and graduate and postgraduate students of geology, applied geology, and mining geology. It will also serve as a reference book for practising civil engineers and professional engineering geologists. The book deals with both the principles and practices of engineering geology. Because of the author’s rich experience of working with various types of engineering projects such as dams, tunnels, bridges, and having been involved in disaster management activities in cases of natural calamities across the world such as earthquakes, landslides, and tsunamis, he has focussed on the practical aspects that will come in handy for geology students. <...>
Planned economy presumes that all undertakings are premeditated and prepared in detail. The main condition for good planning is therefore reliable preparation of materials and a comprehensive knowledge of the problem, with due consideration of every factor involved.
This manual provides guidelines and instructions for performing and documenting field work. The manual is a ready reference for anyone engaged in field-oriented engineering geology or geotechnical engineering. The manual is written for general engineering geology use as well as to meet Reclamation needs. The application of geology to solving engineering problems is emphasized, rather than academic or other aspects of geology <...>
