Abstract
1. Способ сооружения фундамента под машины, заключающийся в заглублении подошвы массивного армированного железобетонного фундамента прямоугольной или призматической балочной в плане формы в грунтовое основание на высоты, но не менее 1 м, при гидроизоляции от вредного воздействия агрессивных грунтовых вод и расположении центра тяжести машины и центра тяжести площади подошвы фундамента на одной вертикали, при этом опорную поверхность фундамента принимают площадью , где Еупр. - модуль упругости грунта, ко - коэффициент формы фундамента в плане, µо - коэффициент Пуассона грунта, Cz - коэффициент упругого равномерного сжатия, отличающийся тем, что опорную поверхность фундамента прямоугольную в плане выполняют с подошвой сферической выпуклой формы радиусом , где d - диаметр отпечатка заглубленной сферы на поверхности грунта, - угол сектора упругого полуконтакта сферы с грунтом, - давление структурной прочности грунта на растяжение, φ - угол внутреннего трения и с - удельное сцепление грунта, - критическое давление под центром сферы, среднее допускаемое давление на упругое грунтовое основание рассчитывают как , где - радиус эпюры контактных напряжений под центром сферы, f=1-cos ψупр., при этом сферу фундамента заглубляют на величину при ее осадке , где Ео - модуль объемной деформации грунта, при этом опорную сферическую поверхность предохраняют от смещений с проворотом и от опрокидывания под действием внешней динамической нагрузки путем увеличения краевой горизонтальной опорной части прямоугольного в плане фундамента, выступающей за края сферической опорной центральной поверхности, либо путем анкеровки фундамент�1. A method of constructing a foundation for a machine, which consists in deepening the soles of a massive reinforced concrete foundation of a rectangular or prismatic beam in terms of shape into a soil base at a height of at least 1 m, with waterproofing from the harmful effects of aggressive groundwater and the location of the center of gravity of the machine and center the severity of the area of the sole of the foundation on the same vertical, while the supporting surface of the foundation is taken to be the area where Eup. is the soil elasticity modulus, ko is the plan shape coefficient of the foundation, μo is the soil Poisson's ratio, Cz is the uniform elastic compression coefficient, characterized in that the support surface of the foundation is rectangular in plan with a spherical sole with a radius of radius, where d is the diameter of the indentation spheres on the soil surface, is the angle of the sector of the elastic half-contact of the sphere with the soil, is the pressure of the structural strength of the soil in tension, φ is the angle of internal friction and c is the specific adhesion of the soil, is the critical pressure under the center of the sphere, the average permissible pressure on the elastic soil foundation is calculated as, where is the radius of the contact stress diagram under the center of the sphere, f = 1-cos ψupr., while the foundation sphere is deepened by the amount when it is settled, where Ео is the bulk modulus of soil in this case, the supporting spherical surface is protected from rotational displacements and from tipping over under the action of an external dynamic load by increasing the horizontal horizontal supporting part of the foundation, rectangular in plan, protruding beyond the edges of the spherical central polar surface by anchoring or foundation
