摘要
根据地下资源开发地区岩层与地表移动机理,研究了地面沉陷对路基产生的破坏影响,分析、总结了路基沉陷特征,给出了确定路基和矿柱强度及稳定性的验算方法,以及路基出现坍塌或滑坡等灾害事故的评估方法,提出了地面沉陷区路基防治技术,并列举了治理路基沉陷的例子。
The mechanism of ground movement in underground mining area is expound in this pape.The destructive effects on roadbed for mining subsidence are researched.The subsidence characteristics of roadbed are analyzed and summarized.The checking methods for the strength and stability of roadbed and ore pillars are give.The methods to evaluate disastrous accidents caused by roadbed collapse and landslide are presented.The measures for preventing and maintaining of roadbed in mining subsidence area are put forward.Lastly,a practical example to predict and control roadbed subsidence is given.
