| 摘 要： | 门头沟是北京地区的主要产煤区,地下有许多煤层采空区,其变形破坏可在地表引起比较严重的地面塌陷、地裂缝以及滑坡等地质灾害,对公路及建筑物等造成严重破坏。在采空区探测方面,物探方法因其精确、高效、施工方便且对地表无破坏性等优势而成为一种常用的重要手段。但针对一个特定的地区,采取不同的物探方法或不同的技术参数,其探测效果大不相同。本文在北京门头沟棚户区改造项目前期勘查工作的基础上,结合工程实例,对区内小窑采空区的变形特征及地球物理特征进行了认真分析,并对不同的物探手段在小窑采空区探测方面的应用和效果进行了初步探讨,这对今后有效开展采空区勘查工作具有一定的指导意义。

| Abstract: | Mentougou County was the main coal-producing area in Beijing area.There were many underground cavities caused by coal mining,whose deformation could cause more serious geological disasters such as the ground subsidence,ground fissures and landslides and affected the safety of highways and buildings.In the mined-out area exploration,the geophysical method was one of the important means because of its accuracy,efficiency,convenience and easy operation.However,for a specific area,different geophysical methods ... |
