alluvial deposits
解釋
沖積層-
The elementary idea of the reference units method can be described as follows : firstly, by the setting of double series of reference units, we can control the highest and lowest land quality class of each village or town ; secondly, the class of the arable land will be get through the contrast between the arable land with the reference unit which has been selected in the same area, the difference in quality is the key factor to classify the land. the results show, 87. 6 % of the lands from i to iii distribute on alluvial and lacustrine plains, where the associated soils are mainly grey fulvo - aquic and calcareous concretions black ones. and 61. 4 % of them from iv to vi distribute on slightly rolling parts with mainly yellow - cinnamon soil developed from the diluvial and slope deposits

The researches of dynamic behavior and liquefaction potential of saturated sands have been further. however, more and more macroscopic liquefaction phenomena and experimental investigations show that different depositional environments lead to different structure of soils, while the influence of structure property of soils on liquefaction resistance is no less than that of density and consolidation stress and so on. ancient alluvial flat deposits, namely recently deposited soils, are easier liquefaction during earthquake
對於一般飽和砂土的動力特性和液化勢的研究已比較深入，然而，愈益增多的宏觀現象和試驗研究表明，由於土的沉積環境不同而導致土的結構性的差異，而土的結構性對抗液化能力的影響並不亞於密度、固結壓力等因素，古河漫灘堆積物即新近沉積土在地震當中更容易液化。 -
