Description
Изобретение относитс к области инженерно-геологических изысканий дл строительства , в частности к лабораторным и полевым исследовани м сжимаемости грунтов .The invention relates to the field of engineering and geological surveys for construction, in particular to laboratory and field studies of the compressibility of soils.
Цель изобретени - повышение точности и производительности испытаний.The purpose of the invention is to improve the accuracy and performance of the tests.
Способ осуществл ют следуюп1им образом .The method is carried out as follows.
По данным инженерно-геологических изысканий определ ют мощность фильтрующего сло основани будущего сооружени и наименование грунта, слагающего этот слой. Замер ют высоту образца грунта из исследуемого сло . Образец помещают в компрессионный прибор и производ т равномерное и непрерывное увеличение нагрузки на образец до макси гального заданногоAccording to the engineering and geological surveys, the thickness of the filter bed of the base of the future structure and the name of the soil composing this layer are determined. The height of the soil sample from the test layer is measured. The sample is placed in a compression device and a uniform and continuous increase in the load on the sample is made up to the maximum specified
ее значени со скоростью, определ емой соотношением:its value with a speed determined by the relation:
(),()
где А„ - скорость нагружени основани . Па/ч;where A, is the loading rate of the base. Pa / h;
Н„ - мощность исследуемого фильтрующего сло основани , м;Н „- power of the studied filtering layer of the base, m;
Н - высота образца грунта, м.H - the height of the soil sample, m
При этом скорость нагружени основани АО определ ют, руководству сь проектом сооружени , но при назначении скорости увеличени нагрузки на образец в водонасыщенном состо нии ее значени ограничивают пределами: дл супеси не более 0,33, дл суглинков не более 0,09 и дл глин не более 0,009 МПа/ч. Дл песчаныхAt the same time, the loading speed of the base AO is determined by the management of the construction project, but when assigning the rate of increase of the load on the sample in a water-saturated state, its values are limited to: for sandy loam no more than 0.33, for loams no more than 0.09 and for clay more than 0,009 MPa / h For sandy

грунтов эта скорость может превышать 0,33 МПа/ч.Soils this speed can exceed 0.33 MPa / h.
По достижении максимального заданного значени нагрузки. №а образец ее увеличение прекращают.Upon reaching the maximum specified load value. No. a sample of its increase stop.
В течение всего процесса испытаний осуществл ют запись нагрузок на образец и соответствеющих им деформаций образца . После достижени стабилизации деформаций образца испытани прекращают.During the entire test process, the loads on the specimen and the corresponding deformations of the specimen are recorded. After the stabilization of the deformations of the sample is reached, the tests are stopped.
Руководству сь результатами записи нагрузок на образец и его соответствующих деформаций известными способами вычисл ют модуль деформации, устанавливают значени структурной прочности и начального просадочного давлени .The management of the results of recording the loads on the sample and its corresponding deformations is calculated using known methods, and the values of the structural strength and the initial subsidence pressure are established.
Эффективность использовани способа определ етс тем, что увеличение нагрузки и консолидаци грунта происход т одновременно в режиме, исключающем разрушение структуры минерального скелета вследствие резкого увеличени нагрузки и соответствующего резкого увеличени нейтральных давлений в норовой жидкости . При этом услови консолидации образца и фильтрующего сло под сооружением подобны, что повыщает достоверность результатов. Одновременно значительно сокращаетс длительность испытаний .The efficiency of using the method is determined by the fact that an increase in the load and consolidation of the soil occur simultaneously in a mode that eliminates the destruction of the mineral skeleton structure due to a sharp increase in load and a corresponding sharp increase in neutral pressures in the burnt liquid. In this case, the conditions of consolidation of the sample and the filter layer under the structure are similar, which increases the reliability of the results. At the same time, the test duration is significantly reduced.
