摘要
广州市轨道交通六号线萝岗车辆段场坪东侧开挖形成高度近60 m的人工边坡,为保证边坡稳定,防止水土流失,避免次生灾害发生,开展了边坡稳定性分析及加固防护技术研究。数值分析结果表明:按照安全适用、技术先进、经济合理、保护环境的原则,自上而下逐级开挖边坡,采取放坡、挡土墙、锚索(杆)格构护坡、种草、截排水、主动网防护等综合措施进行边坡加固与防护是可行的。
A 60 mhigh slope was excavated on the eastern side of Luogang depot of G uangzhou urban rail transit line 6. In order to prevent soil erosion and avoid the occurrence of secondary disasters,the slope stability was analyzed and the corresponding reinforcement and protection measures were studied. The results of numerical analysis shows that the slope reinforcement and protection can be realized. In accordance with the principle of applicable safety,advanced technology,economic rationality and environmental protection,a stepped top-down excavation was suggested. A comprehensive reinforcement and protection measures includes sloping,retaining wall,lattice anchor( rod) slope protection,grasses,drainage and positive net protection.
