EXPERIMENTAL RULES OF SLAKING FOR K0 COMPRESSED CLAY AND ITS DESCRIPTION
-
摘要: 通过对取自奥林匹克森林公园的土进行的干燥状态和饱和状态下的K0压缩试验及湿化试验,得出以下结论:在e-lgp图中:1)正常压密干土在各荷载下湿化,其孔隙比均落在饱和泥浆压缩线上;2)同一前期固结压力下,不同超压密比的干土湿化后,其孔隙比也近似落在一条直线上。依据湿化试验的结果,对K0状态下天然土的湿化行为给出数学描述,并对试验数据进行预测,结果表明:预测结果与试验结果基本吻合。Abstract: In this paper, from results of K 0 compression tests and slaking tests on both dry clay and saturated clay in Olympic Park, some conclusions are obtained: in e-lgp paragraph, when the normal compressed dry clay is wetted under different stresses, the void ratios all reach compression line of saturated clay; while different over compressed dry clay in the same pre-consolidation pressure is wetted, the void ratios also reach one line approx imately. Concluding from the results of slaking tests, a mathematical description is worked out to describe wetting deformations under K0 compression. Using this mathematic description, a prediction for wetting deformations is given out and it agree well with the tests results.
