Description
Изобретение относится к области исследования несущей способности забивных свай в полевых условиях. . .The invention relates to the field of research of the bearing capacity of driven piles in the field. . .
Известен способ определения несущей способности забивных свай путем приложения ударной нагрузки к свае и измерения вер- 5 тикального ее перемещения, по которому вычисляют с учетом коэффициента однородности грунта несущую способность сваи по грунту [1].There is a method of determining the bearing capacity of driven piles by applying an impact load to the pile and measuring its vertical displacement, according to which, taking into account the uniformity coefficient of the soil, the bearing capacity of the pile on the ground is calculated [1].
Наиболее близким к предлагаемому из 10 известных является способ определения несущей способности сваи путем приложения к свае ударной нагрузки и расчета несущей способности ][2]. jClosest to the proposed of the 10 known is a method for determining the bearing capacity of piles by applying shock to the pile and calculating the bearing capacity] [2]. j
Недостатками этих способов являются 15 трудоемкость и длительность определения несущей способности свай.The disadvantages of these methods are 15 the complexity and duration of determining the bearing capacity of piles.
Цель изобретения — сокращение времени определения.The purpose of the invention is the reduction of determination time.
Достигается цель тем, что в процессе приложения к свае ударной нагрузки предлагаемым способом измеряют упругое вертикальное перемещение поверхности груп20 та, граничащей со сваей, а несущую способность сваи рассчитывают по формулеThe goal is achieved by the fact that in the process of applying shock to the pile, the proposed method measures the elastic vertical displacement of the surface of the group adjacent to the pile, and the bearing capacity of the piles is calculated by the formula
Р = КаКоАо, где Р — несущая способность сваи;P = KaKoAo, where P is the bearing capacity of the pile;
Кг — коэффициент пропорциональности, зависящий от грунтовых условий;Kg - coefficient of proportionality, depending on soil conditions;
К« —коэффициент однородности грунта;K "is the coefficient of soil uniformity;
Ао —упругое вертикальное перемещение поверхности грунта, граничащей со сваей.And o — elastic vertical displacement of the surface of the soil bordering the pile.
Предлагаемый способ осуществляется следующим образом.The proposed method is as follows.
На определенном расстоянии от точки погружения сваи, например на расстоянии 10—15 ее диаметров, устанавливают на поверхности грунта вибродатчики, подключенные к регистрирующему устройству. Наносят по свае удар молотом и измеряют вертикальное перемещение (Ав ) поверхности грунта, граничащей со сваей, по которому определяют несущую способность сваи, используя приведенную формулу.At a certain distance from the immersion point of the pile, for example, at a distance of 10-15 diameters of it, vibration sensors are mounted on the ground surface connected to a recording device. The hammer is struck on the pile and the vertical displacement (A in ) of the soil surface, bordering the pile, is measured, by which the bearing capacity of the pile is determined using the above formula.
