坝基粉土液化的影响因素及防治对策
Influencing Factors of Silt Liquefaction and Prevention Measures for Dam Foundation
【摘要】 针对地处强震区中拟建的王庆坨水库坝长、坝基粉土分布广且厚极易造成砂土液化问题,对重塑粉土做了振动三轴仪试验,从地震往返作用力、固结压力、初始剪应力、干密度、土结构、颗粒组成等方面研究了粉土液化的影响程度,提出了合理、经济、可行的液化防治对策。
【Abstract】 Wangqingtuo reservoir located meizoseismal area has characteristics of long dam and widespread silt in dam foundation,which leads to sand soil liquefaction easily.Reconstruction silt has been done experiment with vibration triaxial apparatus.The influence of cyclic acting force,confining pressure,initial shear stress,dry density,soil structure and grain composition on silt soil liquefaction is analyzed.Thus,the reasonable,feasible and economic liquefied prevention measures are proposed.
