Инженерные изыскания коридоров линейных коммуникаций с учётом геотехнического мониторинга бугров пучения

Abstract

The necessity of oil and gas fields arrangement in the Extreme North and developing updated edition of rules’ for making engineering surveys codes, taking into account the specific features of the oil and gas fields territories with heaving mounds of permafrost (MMP) is considered in details. The developed models of temperature fields enable predicting possible deformation changes in the geospatial position of the underground and aboveground components of the heaving mounds. It is recommended that the corridor of linear communications be located at least 50 meters from the underground component of the heaving mound and 100 meters from the upper line of the intersection of the heaving mound with the earth’s surface. A new formula for determining the depth of thawing is proposed, taking into account the amount of seasonal thawing and the lateral influence of the heave hill. The research results are introduced in the production of engineering surveys in Samburg, Centillica and Yamburg.
