摘要
贵阳市某高校规划筹建大数据学院建筑,场地位于原采石场位置,建筑一侧紧邻既有岩质边坡,岩体为硬质岩,岩层呈切向-反向,边坡高度超过规范使用范围,为确保坡底拟建建筑物安全,对边坡进行治理。以该高校超限岩质建筑边坡为例,重点研究永久性超限岩质边坡的防护措施,根据边坡勘察资料并结合现场踏勘,通过稳定性计算分析边坡稳定性,并根据规范计算岩石侧压力,结合边坡高度,采用锚索(锚杆)结合格栅梁防护的方案。
A university in Guiyang City plans to build a school building,and the site was originally a quarry.One side of the building is close to an existing hard rock slope with a tangential to reverse stratum,and the slope height exceeds the standard limit.To ensure the safety of the proposed building at the slope bottom,the slope needs to be treated.On this basis,the protective measures for the permanent over-limit hard slope are mainly studied.According to the slope investigation data and field survey,the slope stability is analyzed by the stability calculation,and the lateral stress of the rock is calculated according to the specification.Considering the slope height,the protection scheme combining anchor cable(anchor bolt)with grid beam is adopted.
