| 摘 要： | 田德铁路位于桂西南右江盆地及岩溶峰林洼地区，其中线路在CIK6＋200-CIK7＋000之间横穿小龙煤矿中部，由于采空区的不断下沉和地表变形，使过境公路及周围建筑物产生了较为严重的病害，线路在小龙村地段存在横穿煤矿方案和绕行方案的比选问题。通过对小龙煤矿采空区地质状况、地表沉降及稳定性的分析与评价，推荐绕行方案（CK方案）为贯通方案。

| Abstract: | Tiandong-Debao railway is located in the Karst depression and Youjiang basin of southwestern Guangxi, which passes through the mining are at CIK6 ＋ 200 - CIK7 ＋ 000. Due to constant subsidence and ground deformation in the depletion region, transit highways and surrounding buildings have got severe diseases. During the railway construction in Xiaolongcun section, comparison and selection were carried out between two schemes： one is that the railway passes through the depletion region, and the other is detouring. This paper researches and analyzes the geophysical conditions and land subsidence of the depletion region, and appraises its stability. Finally, the detouring scheme （CK scheme） is selected. |
