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。Liquefaction of saturated sands is a greatly complicated phenomenon. its generation, development and dissipation are restricted by physical property, stresscondition and boundary condition of soils. in addition, there are a lot of influencing factors such as density, structure property ， clay content, degree of saturation, gradation, hydraulic conductivity, initial stress condition and dynamic load character and so on
砂土液化是一種相當復雜的現象，它的產生、發展和消散主要由土的物理性質、受力狀態和邊界條件所制約，存在許多影響因素，例如土的密度、土的結構性、粘粒含量、飽和度、級配、透水性能以及初始應力狀態和動荷載特徵等。5. seasonal variation of co total column in beijing is greatly affected by the major co source with similar season variation. the changes in co column amount are closely related to meteorological conditions, mainly including atmospheric stability, wind speed and wind direction
