Description

Изобретение относитс  к строительству, в частности, к инженерно-геологическим изыскани м . Наиболее близким к предлагаемому  вл етс  способ исследовани  прочностных свойств грун тов при сдвиге, включающий размещение штам па в исследуемом грунте, извлечение его из грунта, измерение усили  извлечени , площади поверхности сдвига и определение характеристик грунта 1. Недостатком известного способа  вл етс  трудоемкость и невысока  точность. Цель изобретени  - снижение трудоемкости и повышение точности исследований насыпных грунтов. Указанна  цель достигаетс  тем, что в способе исследовани  прочностных свойств грунта при сдвиге, включающем размещение штампа в исследуемом грунте, извлечение его из грунта , измерение усили  извлечени , площади. Поверхностного сдвига и определение характери тик грунта, при размещении штампа в грунте осуществл ют отсыпку нанего грунта с пог следующим его уплотнением. Способ осуществл ют следующим образом. На ранее уплотненный слой грунта устанавливают штамп с вертикальной т гой, длина которой несколько превышает толщину отсыпаемого сло  грунта и конец которой соединен с силовым устройством. Затем производ т отсыпку сло  и его уплотнение до заданной плотности, определ емой, например, методом режущих колец, после чего прикладывают к штампу вертикальное усилие и производ т выпор грунта. Одновременно измер ют усилие вырыва штампа. Данное испытание производ т при различных начальных плотност х грунта. По результатам испытаний стро т график зависимости предельного сопротивлени  сдвига от различной начальной плотности насыпного грунта и графо-аналитическим способом определ ют его козффициент внутреннего трени  и сцепление. Применение изобретени  позволит снизить трудоемкость и повысить точность исследований.The invention relates to the construction, in particular, to engineering and geological surveys. The closest to the present invention is a method for investigating the strength properties of soils during shear, including placing the strains in the soil being studied, removing it from the soil, measuring the extraction force, shear surface area and determining the soil characteristics 1. . The purpose of the invention is to reduce the labor intensity and increase the accuracy of bulk soil research. This goal is achieved by the fact that in the method of investigating the strength properties of the soil during shear, including placing the punch in the soil under study, removing it from the soil, measuring the extraction force, area. Surface shear and characterization of the soil, when the stamp is placed in the soil, dumping of the soil is carried out with its subsequent compaction. The method is carried out as follows. A stamp with a vertical thrust, the length of which slightly exceeds the thickness of the soil layer to be filled, and the end of which is connected to the power device, is placed on the previously compacted soil layer. Then, the layer is dumped and compacted to a given density, which is determined, for example, by the method of cutting rings, after which a vertical force is applied to the die and the ground is ported. At the same time, the punch pull force is measured. This test is performed at various initial soil densities. According to the test results, a graph of the dependence of the ultimate shear resistance on different initial density of the bulk of the soil is plotted and its coefficient of internal friction and adhesion is determined by the graph-analytical method. The application of the invention will reduce the complexity and improve the accuracy of research.
