| 摘 要： | 以长沙市煤炭坝地区为例,重点研究岩溶塌陷灾害的空间分布特征及岩溶发育程度控制因素。综合分析表明,区内岩溶发育强弱与岩溶塌陷灾害发育区域基本一致,平面上呈现“环状分布、北东向辐射”的特征,断裂带区域岩溶相对较发育;在垂向100 m深度范围内强发育,随深度增加而减弱,但靠近断层地带,岩溶局部强发育。

| Abstract: | Taking the Meitanba area of Changsha city as an example,the spatial distribution characteristics of karst collapse disasters and the controlling factors of karst development degree are mainly summarized.The research result shows that,the spatial trend of karstificaiton intensity has a high spatial correlation with karst collapse,which presents a spatial feature of“circular distribution and northeast radiation”along the main faults.In the vertical direction,karst points are mainly concentrated within 100m near the surface,and the intensity of karst shows an obvious decreasing trend from the surface to the deep,while it will show a local opposite trend when faults are encountered. |
