| 中文摘要 | 金龙山地区位于四川省雅砻江二滩水电站库首左岸。区内海拔1000—2700米;重点研究区海拔<1730米,面积近1.3平方公里。本区滑坡顺层发育,以蠕滑方式为主,成条成群分布,新老俱全,厚度各异(巨厚—表层),规模不一。控制坡体蠕滑和滑动的主要是层面(或似层面)、层间错动带和中缓倾角裂隙。据滑坡活动状况的不同,将全区分为三个滑坡区:Ⅰ区是多级古滑坡区(方量约200万立方米);Ⅱ区是蠕滑区(方量约2000万立方米);Ⅲ区是浅-表层残坡积层滑坡区。 |
| 英文摘要 | Jinlongshan region beside a dam area is locaded on the left bank of the reservoir at Ertan Hydropower Station of the Yalongjiang River, Sichuan Province. Altitude is at 1000-2700m. The main research region is 1. 3km2 (< 1730m ).The research region is divided 3 Landslide area. The I area is old and multistep landslide. There are a great many landslides of the eluvium and deluvium in the I area.The Ⅱ area is a creeping slide area. The creep-slide phenomena in the mine blocks of the claystone ore district ( 1520-1430m ) presented: 1.the shear zone on the top surface of the clay-stone;2. the vertical dikes are shared,and they slided along the top surface of the claystone;3. the story ckeavage zone on the top surface of the claystone; 4. the cracking arch ring of the mine blocks on the top surface of the claystone; 5. the alluvial gravels with groove and slikenside in the mine bock. According to the explortion data in the front of Ⅱarea,the creep-slide sureface on the top surface of the claystone cross obliquely the overlying limestone and basalt. At the present time,the creep-slide sureface occurred along the unloading cracks is developing into a slide plane.The length of the creep-slide body in theⅡarea is 1200m,the average width is 200m,the average thickness is 80m,the volume is about 20Mm3.Jinlongshan region exists a complex landslide groups. The landslide characteristics are multilayer , piece-wise, blocking, multi-stage, and multistep. |
