拟扩建新厂区边坡岩体类型为Ⅳ,边坡工程安全等级为二级,该岩体可见共有六组节理发育。外倾节理一组,产状为280°~300°∠42°~75°与边坡坡向277°几乎一致,经计算边坡稳定性系数均小于1.30,为不稳定边坡。经分析拟建边坡小于40°时趋于稳定,大于40°时为不稳定边坡。

Slope rock type of the new plant expansion isⅣ, slope safety grade two level, the rock body has six sets joints. A set of extraverted joint, the occurrence 280 °~300 °,∠42 °~75 ° almost same to slope 277 °. By calculating the slope stability coefifcient is less than 1.30, is the unstable slope. Through the analysis, the slope less than 40 ° tends to be stable, more than 40 °is unstable slope.
