摘要
津蓟高速公路肘各庄路段穿越原肘各庄村花岗岩采石场(已废弃),该废弃采石场存在崩塌地质灾害隐患,已有坡面风化岩体崩落,影响或威胁了高速公路的正常运营。尝试应用极射赤平投影分析崩塌体的稳定性,应用落石弹跳运动轨迹曲线方程划分崩塌体威胁范围,并且针对性地提出了治理方案。
The Zhougezhuagn section of Jinji expressway cuts through an abandoned granite quarry near the Zhougezhuagn village. There is a risk of collapse of geological hazards due to some weathered rocks on slope had avalanched, which is threatening the normal operation of expressway. The paper tries to analyze the stability of the collapsed body by polar stereographic projection, define the affecting scope of collapsed body applying rockfall bounce trajectory curve equation, and puts forward the rational control scheme.
