Description
(54) СПОСОБ ОПРЕДЕЛЕНИЯ ПРОЧНОСТНЫХ ХАРАКТЕРИСТИК(54) METHOD FOR DETERMINING STRENGTH FEATURES
II
Изобретение относитс к инженерно-строительным изыскани м и используетс дл определени характеристик механических свойств водонасыщенных грунтов, расположенных ниже уровн грунтовых вод.The invention relates to engineering and construction surveys and is used to determine the characteristics of the mechanical properties of water-saturated soils located below the groundwater level.
Известен способ испытани грунтов, включающий погружение зонда, измерение нормального давлени на ствол и сопротивлени грунта сдвигу по боковой поверхности путем поворота зонда вокруг вертикальной оси, причем по полученным даннымсуд т о прочности грунта (1).There is a known method for testing soils, including immersing a probe, measuring the normal pressure on the barrel and ground resistance to shear along a lateral surface by rotating the probe around a vertical axis, and according to the data obtained, the ground strength (1) is obtained.
Недостаток этого способа состоит в сложности установлени функциональной св зи между нормальным давлением и сопротивлением сдвигу, что затрудн ет определение прочностных характеристик грунтов - угла внутреннего трени и сцеплени .The disadvantage of this method is the difficulty of establishing a functional relationship between normal pressure and shear resistance, which makes it difficult to determine the strength characteristics of soils — the angle of internal friction and adhesion.
Известен также способ испытани грунтов , включающий погружение зонда и одновременно с ним металлических стержневых электродов, причем после замера нормального давлени и сопротивлени сдвигу на зонд и электроды подают посто нный ток и осуществл ют дополнительные измеГРУНТАThere is also known a method for testing soils, which includes immersing the probe and simultaneously with it metal rod electrodes, and after measuring the normal pressure and shear resistance, constant current is supplied to the probe and electrodes and UNDER measuring
рени . При этом измен етс нормальное давление на ствол, что обеспечивает возможность установлени функциональной, св зи между нормальным давлением и сопротивлением грунта сдвигу 2.reni. This changes the normal pressure on the barrel, which makes it possible to establish a functional connection between the normal pressure and the resistance of the soil to the shear 2.
Однако известный способ применим дл испытани только глинистых водонасыщенных грунтов.However, the known method is applicable for testing only water-saturated clay soils.
Цель изобретени - повышение точ-ности определени прочностных параметров песчаных и глинистых грунтов, залегающих ниже уровн грунтовых вод.The purpose of the invention is to improve the accuracy of determining the strength parameters of sandy and clayey soils that lie below the groundwater level.
Поставленна цель достигаетс тем, что согласно способу определени прочностных характеристик грунта, включающему погружение зонда, измерение нормального давлени и сопротивлени сдвигу путем поворота зонда вокруг вертикальной оси, после измерени нормального давлени и сопротивлени сдвига производ т откачку воды из грунта с помощью иглофильтров с последующим даполнительным измерением нормального давлени и сдвига. ,.This goal is achieved in that according to the method of determining the strength characteristics of the soil, including immersion of the probe, measurement of normal pressure and shear resistance by rotating the probe around the vertical axis, after measuring the normal pressure and shear resistance, water is pumped out of the soil using needle filters and subsequent additional measurement normal pressure and shear. ,
