【摘要】 采空区是公路建设中一种特殊的地质病害,特别是小煤窑采空区,由于无规划、无序、反复地开挖,故小煤窑采空区勘察与评价有较多不确定性。在公路工程地质勘察中采用综合勘察方法,查明采空区分布范围并评价其对公路工程危害程度及稳定性,对高速公路建设非常重要。本文结合安徽省铜陵至汤口高速公路具体工程实例,探讨小煤窑采空区综合勘察与评价。更多还原

【Abstract】 The mined-out area is an especial geotechnical hazard to highway.Because of no plan,no management and repeatedly mining,there exist some uncertainty and difficulty in assessing stability of small coalfield mined-out areas.It is very important to investigate the mined-out areas for evaluating its hazard to highway by applying the integrative geotechnical investigation method.Taking the Tongling-Tangkou highway as an example,the geotechnical investigation and stability evaluation for small coalfield mined-out areas are discussed in this paper.更多还原
