摘要
采空区工程处理范围确定是捆扰通过采空区高速公路建设的难题,目前尚无良好的理论计算确定方法。基于随机介质理论应用于岩土工程领域的研究成果,建立高速公路采空区地面变形计算模型,编制相关计算程序(GSM和POBA),用于耒阳—宜章(耒宜)高速公路采空区地面变形计算,成功解决高速公路采空区地面变形计算问题。提出高速公路地面变形控制指标,将其应用于耒宜高速公路采空区工程处理范围确定实践,为解决实际工程问题提供依据。
The goaf engineering treatment scope determination is one of the highway construction difficult problems,which until now there has no good computation method to settle with.A goaf-above ground surface deformation computation model which is based on the stochastic medium theory;and the achievements of stochastic medium theory′s application to geotechenical domain is set up;and the computation programs（GSM and POBA） are also developed.The computation model and computation programs are applied to Leiyang—Yizhang highway′s goaf ground deformation computation,which successfully solved the high way′s goaf ground deformation computation problems.At the same time,the highway ground deformation controlling indexes and the method to determine goaf engineering treatment scope are provided.The goaf-above ground surface deformation controlling indexes and the goaf treatment scope determination method successfully solved Leiyang—Yizhang highway′s goaf engineering treatment scope determination problem.
