摘要: 在采空区路段上修建高速公路如不处置或者处置不当,采空区路基将在长时间内发生较大的沉降,这将直接 危害其上的构筑物。采用概率积分法分析了万盛一南川高速公路下伏采空区稳定性。研究表明:该高速公路下伏 采空区残余变形大于高速公路允许变形值。结合实际工程情况,提出了采空区注浆的治理措施。通过室内及现场 试验,提出了合理的注浆参数和注浆施工工艺。

关键词: 高速公路, 采空区, 稳定性, 治理措施:注浆参数

Abstract: If the express way constructed above the goaf area was improperly disposed or not disposed , the foundation of the goaf area would have a large settlement in a long time , which would directly harm the structures built above it. The probability integral method was applied to analyze the stability of goaf area under the express way from Wansheng to Nanchuan. The results show that the residual deformation value of the goaf under Wansheng-Nanchuan expressway is heyond the expressway' s allowahle deformation value. 50 the grouting measures at the goaf area are put fonvard with the consideration of actual engineering conditions. The reasonahle parameters of grouting and grouting construction technology are also proposed hy means of lahoratory and site experiments.

Key words: expressway, goaf, stahility, control measures, grouting parameter
