Изобретение относитс  к области исследований строительных свойств скальных грунтов в основании сооружений, в частности гидротехнических .The invention relates to the field of studies of the construction properties of rocky soils at the base of structures, in particular hydrotechnical.

Известен способ определени  водоупорных и механических свойств скального грунта путем нагнетани  воды в исследуе.чыи массив, грунта, создани  нанр жепного состо ни  и измерени  его водопроницаемости и деформативности .There is a known method for determining the waterproof and mechanical properties of rock soil by injecting water into a test mass of the soil, creating a nanotube condition and measuring its water permeability and deformability.

Предлагаемый способ отличаетс  тем, что дл  определепи  в натурных услови х зависимости суффозиоппой и мехапической прочности и водопроницаемости от напр женного состо ни  и фильтрационного режима в исследуемом массиве грунта обуривают целик но замкнутому контуру, а затем, одновременно с нагнетанием воды, подвергают его обжатию осевыми и радиальными нагрузками различной интенсивности.The proposed method is different in that, for natural conditions, the dependencies of suffixiope and mechapic strength and water permeability from the stressed state and filtration mode in the soil mass under study are filled with a fully closed contour, and then, simultaneously with the injection of water, subjected to axial compression radial loads of varying intensity.

На чертеже показана установка дл  реализации описываемого способа.The drawing shows an installation for implementing the described method.

Опытные площадки выбирают в пределах характерных участков исследуемого массива 1. На одном из таких участков с заи;ипцеипой и выравненной поверхностью ироизвод т обуривание целика 2, создава  вокруг него траншею 3. Перед обуриванием целика осуществл ют разбурку центральной скважины 4. Заданное напр женное состо ние скальногоExperimental sites are selected within the characteristic areas of the studied array 1. At one of these areas, with a pipe, a flat surface and a flattened surface, and production of the rear pillar 2, creating a trench around it 3. Before the front pill, the central well is drilled rocky

Осева  нагрузка на целик создаетс  ири помощи гидравлических домкратов 5, передающих усилие на целик черезthe pillar is relieved by axial and lateral loads. The axial load on the rear sight is created by the help of hydraulic jacks 5, which transmit the force to the rear sight through

В случае проведени  эксперимента на открытых площадках упором дл  домкратов может служить опорна  траверса 9 с анкерными т гами 10,The hollow chip 6, the sealing pad / and the leveling cement layer 8. In the case of the experiment in open areas, the support for the jacks can serve as a support yoke 9 with anchor rods 10,

Боковое обжатие целика осуществл етс  гидравлическими подущками П известных конструкций, помещенными в транщеи . Между гидравлической подущкой и целиком помещаетс  дренажна  прослойка 12, например, в виде песчаной или гравийной засыпки . Фильтрационный поток создаетс  путе .м нагнетани  воды в центральную скважину 4, из которой она фильтрует в направлении дренажной прослойки 12.

The side crimping of the rear sight is carried out by hydraulic pods of known structures, placed in trenches. A drainage layer 12 is placed between the hydraulic feeder and the entirety, for example, in the form of a sand or gravel bed. The filtration flow is created by pumping water into the central well 4, from which it filters in the direction of the drainage layer 12. The predetermined pressure is created and the water flow is controlled by any known means, for example
