摘要
某拟建高速公路K4+700~K7+400段存在煤矿采空区,为那龙矿区邓东煤矿、邓丁煤矿,位于广西壮族自治区南宁市西乡塘区那龙镇。通过地面调查、询问走访、高密度电阻率法、地震频率谐振勘探、智能钻孔电视等综合勘察方法,查明了该拟建高速公路下部采空区的埋深、规模、性质,并通过定量分析计算,评价了该段落拟建桥梁、路基的稳定性。
There is a coal mine goaf in the K4+700~K7+400 section of the proposed expressway,namely Dengdong Coal Mine and Dengding Coal Mine in Nalong mining area,which is located in Nalong town,Xixiangtang district,Nanning city,Guangxi Zhuang autonomous region.Through comprehensive survey methods such as ground investigation,inquiry and visit,high-density resistivity method,seismic frequency resonance exploration,intelligent borehole television and etc.,the buried depth,scale and nature of the lower goaf of the proposed expressway are ascertained.The stability of the proposed bridge and subgrade in this section is evaluated through the quantitative analysis and calculation.
