| 摘 要： | 采用DSD 160型电磁式振动三轴试验系统,通过对甘肃白银—兰州高速公路(国道109线)沿线黄土的震陷试验,探讨了该场地黄土在动荷载作用下的震陷特性。利用黄土震陷灾害预测方法和该地区黄土场地地震危险性分析结果,对该公路沿线黄土场地的震陷区进行了判定和评价。这些研究结果可作为该高速公路工程进行抗震设计和地震变形分析的基本依据,对黄土地区其它工程也有一定的参考价值。

| Abstract: | The characteristics of seismic subsidence of the loess along the Baiyin-Lanzhou highway (national line 109) under dynamic loads are studied using DSD-160 electromagnetic dynamic triaxial test system. Using the loess seismic subsidence distaster predicting method and the results of earthquake risk assessment, the seismic subsidence on loess sites were discriminated and evaluated. The obtained results are practical to engineering projects and can be used for the earthquake resistance design and the calculation of loess deformation caused by earthquake for this highway project and other projects in loess areas. |
