Description
(54) СПОСОБ ОЦЕНКИ НЕСУЩЕЙ СПОСОБНОСТИ СВАЙ(54) METHOD FOR ESTIMATING THE CARRYING ABILITY OF PILES
1212
На погруженной эталонной свае закрепл ют соединенный с измерительным прибором датчнк ускорени . После чего по свае нанос т одиночный удар поршнем дизель-молота, сбрасы .ваомый с определенной высоты (1,5 м). При ударе происходит отклонение стреЛКи прибора. По отклонению стрелки из ме|рительного прибора определ ют величину ускорени , с которой эталонна сва погружала1сь в грунт под деЙ1Слвие1М одиночного удара.On the submerged reference pile, the acceleration sensor connected to the gauge is secured. After that, a single piston stroke of a diesel hammer, dumping one from a certain height (1.5 m) is applied to the pile. Upon impact, the instrument deflects. By the deflection of the arrow from the measuring instrument, the magnitude of the acceleration with which the reference pile was immersed in the ground under a single blow.
На испытываемой свае, несуп ую способность которой необходимо определить, закрепл ют датчик ускорени , соединенный с И31мерительным прибором. После этого испытываемую оваю по(двергают одиночному удару nopimHeM дизель-ьмолота. По отклонению стрелки измерительного прибора определ ют ускорение, с которым испытываема сва погружаетс в грунт под действием поршн дизель-молота , сбрасьпваемоЛО с высоты 1,5 м,On the test pile, the inability of which it is necessary to determine, fix the acceleration sensor connected to the I31 measuring device. After that, the test ovay (door of a single impact of nopimHeM diesel-hammer). Acceleration of the measuring instrument determines the acceleration with which the pile is sinking into the ground under the action of a diesel hammer piston, dropped from 1.5 m
Предложенным способом было испытано п ть свай из асего массива. Статические испытани этих свай показали, что две из них имели несуш;ую способность меньшую, чем эталонна , а три сваи большую несуш:ую способность по сравнению с эталонной. Две сваи погружались в грунт с ускорени ми большими , чем эталонна сва . Три сваи погружались :в грунт с ускорени ми меньшими, чем эталонна сва .The proposed method was tested five piles of the array. Static tests of these piles showed that two of them had a laying capacity; their capacity was less than the reference one, and three piles had a greater laying capacity: their capacity compared to the reference one. Two piles were immersed in the ground with accelerations greater than the reference pile. Three piles were immersed: in the ground with accelerations lower than the reference pile.
Таким о-бразом, сваи, которые погружались fl грунт с ускорени ми мееьшими, чем ускорение эталонной сваи, имеют большую несущую спосооность ;по сравнению с эталонной, а сваи, которые погружал;Ись в грунт с ускорени -ми меньшими, чем ускорение эталонной сваи, имеют большую несущую способностьThus, the piles that submerged fl soil with accelerations smaller than the acceleration of the reference pile, have a greater carrying capacity; compared to the reference one, and the piles that submerged; They passed into the ground with acceleration smaller than the acceleration of the reference pile have a large carrying capacity
по сравнению с эталонной.compared to the reference.
Предложенный способ определени несущей способности свай дает возможность судить о величине допустимых нагрузок на оваи в полевых услови х, сокращает врем получеПИЯ результатов испытаний.The proposed method for determining the carrying capacity of piles makes it possible to judge the amount of permissible loads on ovai in field conditions, shortens the time for obtaining test results.
