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。 In view of the dam height of the Wang Qingtuo reservoir located in the strong earthquake zone, the sand foundation is prone to cause liquefaction due to the wide distribution of the silt in the dam foundation and the triaxial vibration test of the remolded silt. From the earthquake reciprocating force , Consolidation pressure, initial shear stress, dry density, soil structure, particle composition and other aspects of the degree of silt liquefaction impact, put forward a reasonable, economical and feasible measures to prevent and control liquefaction.
