Description
II
Изобретение касаетс исследований прочностных и деформационных характеристик грунтовых оснований фундаментоь и предназначено дл изучени их сложног напр женно-деформированного состо ни .The invention relates to studies of the strength and deformation characteristics of soil foundations in the foundations and is intended to study their complex stress-strain state.
Известен прибор трехосного ежа ге содержащий прозрачный цилиндрический корпус, два днища и систему измерени вертикальных перемещений fll .A three-axis hedgehog device is known that contains a transparent cylindrical body, two bottoms and a system for measuring vertical displacements fll.
Наиболее из известных вл етс устройство дл трехосных испытаний Грунтов, включающее комару высокого давлени с образцом грунта, нагрузочное приспособление и измерительное приспособление в виде катетометра С2 .The most well-known is a device for triaxial testing of Soils, including a high-pressure mosquito with a soil sample, a loading device and a measuring device in the form of a C2 cathetometer.
Недостатками известных приборов влютс невозможность замера одновремеф но продольной и поперечной, а также по любому направлению, деформаций образца в его срединной плоскости, нелинейность графика зависимости деформации образца от показаний катетометра в св зи с ци- линдркчностью корпуса прибора и, катаThe disadvantages of the known devices include the impossibility of measuring simultaneously longitudinal and transverse, as well as in any direction, deformations of the sample in its median plane, non-linearity of the plot of the deformation of the sample versus the cathetometer in connection with the cylindrical shape of the instrument body and,
следствие, низка точность измерений де формаций прииспытани х.as a result, the measurement accuracy of deformations in test cases is low.
Целью изобретени вл етс повьпиение точности испытаний за счет замера деформаций образца в различных направлени х.The aim of the invention is to improve the accuracy of the test by measuring the deformations of the sample in different directions.
Это достигаетс тем, что в устройст-ве дл трехосных испытаний грунтов, включающем камеру высокого давлени с образцом грунта, нагрузочное приспособг ление и измерительное приспособление в виде катетометра, камера высокого давлени снабжена закрепленной в ее стенке ппоскопараллельной линзой и призмой Лове (Пехана), размещенной между линзой и катетометром.This is achieved by the fact that in a device for triaxial testing of soils, including a high pressure chamber with a soil sample, a load adaptation and a measuring device in the form of a cathetometer, the high pressure chamber is equipped with an adjacent parallel lens and a Love (Pekhan) prism placed between the lens and the cathetometer.
Плоскопараллельна линза снимает оптические искажени величины перемещений имеющихс на образце датчиков, св занных с цилиндричнос тью корпуса.A plane-parallel lens removes the optical distortions of the magnitude of the displacements of the sensors on the sample associated with the cylindrical body.
