CALCULATION METHOD OF A WIDTH OF STRIPE OF SOAKED LOESSIAL SOIL IN DEEP LEVELS OF MASSIVE WHICH LEADS TO THE START OF THEIR COLLAPSIBLE DEFORMATIONS
Abstract
The article proposes calculation method for determining a width of horizontal strip of soaked collapsible soil in deep levels of soil massive after which the collapsible deformation begins to appear. Soaking of soil leads to two mechanical processes - releasing of vertical pressure in soils inside the stripe and forming of released arch in soil massive above the stripe by arching over it. Calculation method of decrease in vertical pressure in the soil before soaking is defined by special lab methodology during conducting of engineer and geological research of construction field. A height of formed over the stripe arch is calculated by formula of Protodiyakonova M.M. Joint comparative analysis of the formula of remained vertical pressure in soaked soils and the formula of pressure on the stripe created by weight of soils inside the arch allows to define the formula of a width of the stripe under which collapsible deformations of soaked soils will occur.
