Modern problems in regional monitoring оf underground waters

Article preview

The new situation with the carrying out of monitoring of underground waters on regional level was mainly caused by two reasons: 1) new regulations on the preservation of the environment were approved; the present water Regulations are being renewed; 2) studying of regime-forming factors of underground waters (geological, cosmic, climatic, biological, hydrological and technogenic) testify to the urgent necessity of introducing certain amendments into the system and maintainance of monitoring of underground waters.

Анализ инженерно-геологических условий территории учебно-производственного полигона СПГГИ (ТУ) в поселке Кавголово

Article preview

Новая инновационная программа Горного института предусматривает организацию круглогодично действующего полигона в пос.Кавголово Ленинградской области. На нем планируется строительство новых корпусов для обучения и проживания студентов. Для осуществления строительства проведены исследования силами сотрудников кафедры гидрогеологии и инженерной геологии СПГГИ (ТУ) совместно с изыскательской организацией «СУ-299». На основании анализа архивных и литературных источников и результатов изысканий оценены инженерно-геологические условия и гидрогеологическое строение полигона, получены показатели физико-механических свойств песчано-глинистых пород основания проектируемых зданий. Материалы будут использованы при проведении учебной практики со студентами специальности «Поиски и разведка подземных вод и инженерно-геологические изыскания».

Инженерно-геологические особенности проектирования и строительства в санкт-петербурге подземных канализационных коллекторов методом микротоннелирования

Article preview

в концепции развития Санкт-Петербурга важное место занимает усовершенствование генеральной схемы канализации города, в том числе реконструкция старых и строительство новых подземных канализационных коллекторов. В связи с пестротой и сложностью инженерно-геологических и гидрогеологических условий Санкт-Петербурга строительство таких подземных сооружений представляет определенные трудности. Дан краткий обзор текущего состояния канализационной сети Санкт-Петербурга. Показаны особенности инженерно-геологических и гидрогеологических условий строительства в разных районах города подземных канализационных коллекторов способом микротоннелирования. Сформулированы основные положения по изучению условий строительства и эксплуатации данных сооружений.

Engineering-geological and geoecological studies of the impact of operational factors on the stability of civil and industrial structures

Article preview

Statistical data on the reasons of buildings and structures transition to emergency and pre-emergency state are analyzed. In more than 60 % of cases the loss of stability of structures is observed as a result of activation of various factors acting during operation of buildings. The results of experimental studies showing the negative transformation of sand-clay soils under the influence of sewage runoff and the activation of microbial activity are presented. Empirical dependencies of changes in the coefficient of filtration of sands and strength of clayey soils when the bacterial mass increases are given. The role of organic pollutants in changing the redox conditions in the city underground space has been analyzed. The recommendation of the necessity to take into account the technology of industrial production in the practice of engineering surveys is given.

Technogenic evolution of underground space in Saint Petersburg: causes and consequences

Article preview

Natural and technogenic factors determining the evolution and destabilization of the geo-ecological state of the underground space of St. Petersburg are analyzed. Special attention is paid to buried marshes, drainage network and groundwater pollution as the least stable parts of the underground space. The main pollutants of the city are sewage and buried wastes, which bring not only a large amount of organic substances easily assimilated by microorganisms, but also additional microflora. Since the mid-20th century, petroleum hydrocarbons are considered to be active pollutants in the underground space. Large amounts of organic matter in the underground space leads to the formation of a reducing environment and microbiological activation. Conducted mass sampling of redox potential, determining the features of the chemical composition of groundwater, as well as assessing the bacterial mass in sandy clay sediments of the section indicate the importance of physico-chemical and biochemical processes in the evolution and destabilization of the underground space of the city. As a result of these processes, negative transformation of dispersed soils, leading to the formation of floats, the active development of gas-dynamic phenomena, and a high level of environmental aggressiveness are observed. A special form of corrosion of building materials caused by the activity of microorganisms (bio-corrosion), which enhances chemical, electrochemical and other types of underground exposure, has been analyzed. It was found that more than 50 percent of the total destruction of underground pipelines, foundations, and basement walls is the result of bio-corrosion.

Геоэкологичсекие проблемы трансформации окислительно-восстановительной обстановки в грунтовых водах и дисперсных породах

Article preview

Проанализированы природные и техногенные факторы формирования окислительно-восстановительных условий в обводненной толще дисперсных пород. Показано влияние восстановительной обстановки и активности микробиоло­гической деятельности на изменение состава и физико-ме­ханических свойств песчано-глинистых отложений. Приведены примеры трансформации пород при загрязне­ нии грунтовых вод и пород органическими компонентами.
