摘要
湖南省某挖方边坡工程采用土钉加锚杆复合支挡结构,在2005年发生了失稳事故。针对这次事故,分别从土体强度指标的采用、地下水及降雨的影响、设计计算以及施工中存在的问题对边坡失稳原因进行了分析。分析的结果,可对土钉加锚杆复合支挡结构的勘察、设计及施工提供参考。
The soil nail & anchor of complex support structure was applied in a cut slope project in Hunan,which appeared distability accident in 2005.Aming at this accident,the causes analysis was made from these aspects,soil body intensity index,the influence of underwater and rain,design calculation and some existed problems during the construction.The result could provide reference for the surveying,design and construction of the soil nail & anchor of complex support structure.
