摘要
基于现场调研和室内测试，详细研究了青兰高速公路邯郸～涉县段沿线北八特采空区地表塌陷特征，分析了地表塌陷形成的影响因素，探讨了该区地表塌陷形成的宏观和微观机理。这项研究可为拟建高速公路采空区治理方案的选择，以及路基路面、桥梁设计提供科学依据。
On the basis of field investigation and lab. test, the gound collapse characteristics of Beibate mined-out area along Qingdao-Nanzhou Expressway are studied in detail. The influence factors of the gound collapse are analysed. The macro and imicro mechanism of the ground collapse formation is discussed. The study will provide the scientific basis for the selection of the mined-out area treatment schemes of intended expressway and the design of subgrade, pavement and bridge.
