摘要

对索非亚附近细粒组分含量为14.72 ~ 66.88%、单位重量为20.1 ~ 22.5 kN/m3的土壤液化潜力进行了评价。采用循环剪应力法进行评价。分析了Ms = 7.5级、地表最大参考水平加速度αmax(g) = 0.23和无建筑物和设施荷载的自由场地条件下的地震冲击。

The assessment of liquefication potential of water-saturated soils

The liquefaction potential of soils with a content of fine-grained fraction from 14.72 to 66.88% and unit weight from 20.1 to 22.5 kN/m3 in the vicinity of Sofia was evaluated. The assessment was carried out using the cyclic shear stress method. The analysis was performed for a seismic impact with magnitude Ms = 7.5 and at the maximum reference horizontal acceleration at the ground surface αmax(g) = 0.23 and for free field conditions without load from buildings and facilities.
