(54) СПОСОБ ОПРЕДЕЛЕНИЯ КОМПРЕССИОННЫХ ХАРАКТЕРИСТИК ГАЗОСОДЕРЖАЩИХ ВОДОНАСЫЩЕННЫХ(54) METHOD FOR DETERMINING COMPRESSION CHARACTERISTICS OF GAS-CONTAINING WATER-SATURATED
II
Изобретение относитс к области строительства и может быть использовано дл компрессионных испытаний газосодержащих водонасыщенных грунтов.The invention relates to the field of construction and can be used for compression testing of gas-containing water-saturated soils.
Наиболее близким техническим решением вл етс способ определени компрессионных характеристик грунта, включающий отбор образца грунта из массива, размещение образца в эластичной оболочке между дренажными порщн ми, всестороннее сжатие его при помощи гидросистемы и измерение возникающих при этом деформаций и порового давлени на торцах образца 1.The closest technical solution is the method for determining the compression characteristics of the soil, including sampling the soil from an array, placing the sample in an elastic casing between the drainage reservoirs, comprehensively compressing it using a hydraulic system, and measuring the resulting deformations and pore pressure at the ends of sample 1.
Недостатком способа вл етс завыщение деформированных характеристик грунта, которое обусловлено тем, что объем газа в испытываемом образце не соответствует объему его в естественных услови х из-за декомпрессионного расщирени при подъеме грунта на дневную поверхность.The disadvantage of this method is the exaggeration of the deformed characteristics of the soil, which is due to the fact that the volume of gas in the test sample does not correspond to its volume in natural conditions due to decompression expansion when the soil rises to the surface.
Целью изобретени вл етс повышение его точности определени .The aim of the invention is to improve its accuracy of determination.
Поставленна цель достигаетс тем, что в способе определени компрессионныххарактеристик газосодержащих водонасыщенных грунтов, включающем отбор образГРУНТОВThe goal is achieved by the fact that in the method of determining the compression characteristics of gas-containing water-saturated soils, including the selection of the sample GRUNTS
ца грунта из массива, размещение образца грунта с норовым раствором в эластичной оболочке внутри камеры стабилометра между дренажными порщн ми, -обжатие образца с измерением его деформации, на пороговый раствор образца создают и поддерживают посто нным в течение всего опыта давление, равное давлению в месте отбора образца.the soil of the array, placing the soil sample with a burrow solution in the elastic shell inside the stabilometer chamber between the drainage pores, compressing the sample with measuring its deformation, create a pressure solution equal to the pressure at the sampling point for the threshold solution of the sample sample.
На чертеже приведена схема стабилометра дл осуществлени предлагаемого способа .The drawing shows a diagram of a stabilometer for carrying out the proposed method.
Стабилометр состоит из гидравлической камеры 1, гидроизолирующей образец 2 эластичной оболочки 3, дренажных порщней 4, манометра 5, компрессора 6, измерител 7 линейных перемещений, демпферной JC емкости В с манометром 9. Создаваемое в демпферной емкости 8 воздушное давление передаетс через залитый в поддон емкости поровой раствор 10 испытываемого грунта на дренажные поршни 4 через соединительные шланги 11 и 12.The stabilometer consists of a hydraulic chamber 1, a waterproofing sample 2 of an elastic sheath 3, drainage plates 4, a pressure gauge 5, a compressor 6, a meter of 7 linear displacements, a damper tank JC B with a pressure gauge 9. The air pressure generated in the damper tank 8 is transmitted through a tank filled in pore solution 10 of the test soil drainage pistons 4 through the connecting hoses 11 and 12.
Компрессионные испытани газосодержащих водонасыщенных грунтов предлагаемым способом производитс следующим образом.Compression tests of gas-containing water-saturated soils by the proposed method are performed as follows.
