Description
Изобретение относитс к области исследовани физико-механических свойств грунта и может быть использовано дл определени сдвиговых характеристик мерзлых грунтов и льда в лабораторных и полевых услови х .The invention relates to the field of studying the physicomechanical properties of the soil and can be used to determine the shear characteristics of frozen soils and ice in laboratory and field conditions.
Целью изобретени вл етс повышение точности определени сдвиговых характеристик исследуемых материалов , надежности и упрощение конструкции .The aim of the invention is to improve the accuracy of determining the shear characteristics of the materials under study, reliability and simplify the design.
На фиг. 1 изображено предлагаемое устройство, разрезJ на фиг.2 - разрез А-А на фиг. 1.FIG. 1 shows the proposed device, section J in FIG. 2 is section A-A in FIG. one.
Устройство дл испытани мерзлых грунтов и льда на сдвиг содержит раму 1, установленную на столе 2, рабочую камеру, состо щую из неподвижных обойм 3 и 4 и подвижной обой мы 5, соединенной т гами 6 с наружной обоймой подшипников 7 качени , установленных на оси.8. В обоймах размещен образец 9 исследуемого материала , нагружаемый нормальной наг рузкой N. через штамп 10 и сдвигающей нагрузкой Р через шток 11, соединенный с подвижной обоймой 5 при помощи пальца 12. Механизмы дл приложени нагрузок (не показаны) могут быть любыми из известных, наThe device for testing frozen ground and ice for shear comprises a frame 1 mounted on a table 2, a working chamber consisting of stationary collars 3 and 4 and a movable wall 5, connected by means of 6 rollers 7 mounted on an axle. eight. Sample 9 of the material under investigation is placed in cages, loaded with normal load N through a punch 10 and a shear load P through a rod 11 connected to a movable casing 5 with a finger 12. Mechanisms for applying loads (not shown) can be any of the known

пример гидродомкрат, винт, пневмо- чкамера и др.example: hydraulic jack, screw, pneumatic chambers, etc.
Устройство работает следующим образом.The device works as follows.
5 В рабочую камеру помещают образец 9 мерзлого грунта или льда. Необходимьй зазор С между подвижной и неподвижными обоймами рабочей камеры обеспечивают,установкой прокладок 10 требуемой толщины между корпусом и фланцами неподвижных обойм.5 A sample of frozen ground or ice is placed in the working chamber. The necessary clearance C between the movable and fixed collars of the working chamber is ensured by installing gaskets 10 of the required thickness between the casing and the flanges of the fixed collars.
Затем образец 9 нагружают осевой нагрузкой N, нормальной к поверхности сдвига, через штамп 10. Сдвигаю- tS щее усилие Р передают на подвижную обойму 5 через шток 11 сдвигающего механизма и палец 12 и измер ют сило- измерителем (не показан). Сопротивление сдвигу TCO мерзлого Г рунта 20 или льда определ ют по формулеThen, the sample 9 is loaded with an axial load N, normal to the shear surface, through the punch 10. The shifting force P is transmitted to the moving case 5 through the pivot shaft 11 and the pin 12 and measured with a meter (not shown). The resistance to shear of TCO of frozen Grunt 20 or ice is determined by the formula
