摘要
煤矿塌陷区在我国分布较广泛,有些高速公路很难绕过矿区.在煤矿塌陷区内能否建设高速公路关键取决于其路基的稳定性和再变形量.在综合分析大量文献的基础上,从车辆载荷对路基的作用形式、塌陷区路基的再变形机理、计算方法和控制技术等方面对塌陷区路基再变形及控制技术的研究现状进行了综述,指出在煤矿塌陷区路基再变形与控制技术研究中,需要考虑采动覆岩的稳定性及其对路基再变形的影响,根据路基变形的限量指标来反演钻孔注浆的设计参数.
Coal mining subsidence areas are widely distributed in China,thusly it is very difficult for some highways to bypass a mining subsidence area.The construction feasibility of highways in coal mining subsidence regions depends on their roadbed-stability and lurking deformations.Based on lots of literatures and documents reviews,the vehicle loads on the roadbeds,the roadbed-lurking deformation mechanism of a mining subsidence area,the calculating method and control technology of road-lurking deformations and control technologies were reviewed and summarized.The result pointed out that it is necessary to analyze the stability of the collapsed overlying strata and their effects on roadbeds in coal mining subsidence areas,and that borehole grouting design parameters for roadbeds reinforcements can be determined by the inversion of roadbed-lurking deformations limit indexes.
