Discrimination for Sand Layer Liquidation in High Intensity Area
SUN Ling-hui;Xinjiang Water Conservancy & Hydropower Investigation,Design and Research Institute;
The sand layer is distributed on terrace of three grade,which located within the ancient river course,on the right bank of river bed,the chronological time belongs to the Pleistocene series of Quaternary system,overburdened with 10-15 m thick sandy gravel. 10% of the seismic peak ground acceleration is 0. 4 g on the project site in fifty years,corresponding seismic basic intensity is to Ⅸ area.Through the standard penetration of boring,physical exploration and testing,the physical and mechanical property of sandy layer,which distributed on the project dam foundation,was researched,in order to provide more accordance to distinguish the sand layer liquidation,showing that it is also possible there exists liquidation phenomena in the Q3 soil layer of seismic high-intensity area according to the investigated results.
