| 摘 要： | 研山铁矿设计采用露天开采,最终最大边坡高达600m。边坡上部为粉土和粉砂、中砂、卵石、粉质粘土,下部为砂质粘性土和砾质粘性土。由于边坡高,受环境动应力影响因素大,因此分析粉土和粉质粘土层在动应力作用下对变形和强度的影响,对边坡稳定分析具有重要意义。

| Abstract: | Yanshan Iron was designed for using open-pit mining with the maximum height Of the final slope 600m. The height of the slope made of Quaternary System layer is up to 40 m in the east,while it is up to 70 m in the west. It is a high slope. Upper slope is made of silt, silty sand, medium sand, gravel and clay, lower slope is made of sandy clay and gravelly clay. Measuring the changes in the intensity of silt and silty clay layer under the influence of earthquake is important for the slope stability analysis. |
