【摘要】 为了解决在未能掌握详细资料的情况下,能够准确测出采空区具体位置及情况。以山东省枣木高速公路下伏的采空区为研究对象,采用高密度电阻率映像法、高分辨率地震声纳法及声波探测法来综合确定其位置,并用探测结果与钻孔资料相对比分析推出采空区位置。结果表明:高速公路中轴线南北两侧50m范围内,探测区的K3+580～K3+830区段,深度75～90m区间采空区广泛分布。根据采空区和冒落带的相对尺度对应关系,可推断采空区的空间高度3～8m。并针对采空区的探测位置及其特点,提出了相应的治理措施。该联合测定方法准确、可靠,可为今后类似工程提供借鉴。更多还原

【Abstract】 In order to accurately detect the location and condition of goof while failing to grasp the details.In the case of Zaomu highway under goaf,using high density resistivity imaging method,high resolution seismic sonar and acoustic detection method to determine its location,then exploration and drilling result contrast analysis to determine goaf.The results show that: the north and south sides of Expressway central axis 50m range,the detection area K3+580 ~ K3+830 section,a depth of 75 ~ 90m range goaf is widely distributed.According to the corresponding relation of the mining area and the caving zone,we can be infer the gob space at heights of 3 to 8 meters.On the survey of mined-out area location and its characteristics,this paper puts forward the corresponding treatment measures.The joint determination method is accurate and reliable,which can provide reference for the similar engineering in the future.更多还原
