鄂西北山区是国内滑坡地质灾害多发地区,而且目前在鄂西北山区的交通、水电、能源、资源等基础设施建设的力度很大,由此造成及将来可能诱发大量的工程开挖型和水库蓄水型滑坡。因此,尽快建立该地区边(滑)坡的综合分类体系是进一步研究该地区边(滑)坡的发育规律、破坏模式、成灾机制、时空预测及相应防治对策等的基础性工作,为今后深入研究该地区边(滑)坡问题提供基础性成果资料。文中讨论了建立该地区边(滑)坡综合分类体系的基本原则,明确了构建该地区边(滑)坡综合分类体系的3个最主要的特征;提出了该地区边(滑)坡多层次综合分类体系框图;对该地区边(滑)坡主要典型类别划分进行了深入的分析探讨,初步划分出19类典型边坡。并列举了几个典型类别边(滑)坡的工程实例,初步分析了其变形破坏模式和机制,提出了相应的分析计算方法和处治对策建议。
The mountainous area in northwestern Hubei is a frequent area of landslide geological disasters. At present, infrastructure construction of traffic, hydropower, energy, resources and other infrastructure in the mountainous area of northwestern Hubei Province is greatly intensified. As a result, a large number of engineering excavation types and reservoirs may be induced in the future Water landslide. Therefore, to establish a comprehensive classification system of the slope (slippery slope) in the area as soon as possible is the basic work to further study the development law, destruction mode, disaster mechanism, spatio-temporal prediction and corresponding prevention and control measures of the side slope in this area. Depth study of the area (slippery slope) to provide basic information on the results. The paper discusses the basic principles of establishing an integrated classification system for the edge (slippery slope) in the area and defines the three most important features of building an integrated classification system for the edge (slippery slope) in this area. Comprehensive classification system block diagram; the main typical classification of the side slope (slippery slope) in the region conducted in-depth analysis and discussion, the initial classification of 19 typical slopes. The examples of several typical types of slope (slippery slope) are listed. The mode and mechanism of deformation and failure are preliminarily analyzed, and the corresponding methods of analysis and calculation are proposed.
