【摘要】 本文结合连云港庙岭粘性吹填土现场加固试验工程,及在吹填施工结束后的两年中,对吹填土的自重固结特性进行的观测研究,认为吹填土的固结具有大变形非线性的特点,得出吹填土孔隙比与时间半对数关系、固结系数与孔隙比关系、孔隙比与自重固结应力半对数关系,推算出连云港吹填土达到初步固结所需要的时间,可在今后吹填土工程中参考应用。更多还原

【Abstract】 On the basis of in-situ consolidation tests for the pumped clayey soil at Miaoling district of Lianyungang port,and by observation on the pumped soil after, two years consolidation by own weight, this paper points out that the consolidation of pumped soil bears a distinctive feature of non-linear rapid deformation. At the same time, the author obtained some results on the relationship between the void ratio of pumped soil and the deposited durration, with a relation of semi-logarithmic; the relationship between coefficient of consolidation and void ratio of soil; the semi-logarithmic relationship between the void ratio and consolidation stress. Then, time duration required for the pumped soil to get preliminary consolidation was ascertained. All these data are useful reference materials for any pumping project in design.更多还原
