| 摘 要： | 通过不规则荷载与等幅循环荷载作用下的动三轴震陷试验研究结果，对兰州西固工业工的几个黄土场地进行了震陷的预测，其表明，在相同的黄土场地，不同的荷载作用下的震陷量是不相同的；黄土的震陷量在相同土层厚度下，随地震动加速度（或烈度）的增高而增大。

| Abstract: | Based on the result of dynamic triaxail tests on seismic subsidence of undisturbed loess samples under irregular loadings and regular cyclic loadings,the quantities of seismic subsidence on several loess sites in Xigu industrial district of Lanzhou are estimated.It is indicated that the quantities of seismic subsidence of loess are different with different types of loadings on the same site,and the quantity will increase with greater acceleration of ground motion (or intensity) when the loess doposit is of the same depth. |
