( 5 )坝址区河谷岩体力学环境及右岸古滑坡体的稳定问题分析得出：河谷岩体应力场的分析显示，河谷岩体中主应力的方向基本上与现今区域构造应力场的方向一致，在一些特殊地带岩体的主应力值有所降低或增高，特别是在左岸的2000m高程附近及以上，存在有明显张应力区。在未来200年流变计算时步范围内，河谷岩体应力的积累与调整较为有限。同时对滑坡体各种工况条件下的稳定性计算结果表明，右岸古滑坡体在各种工况条件下是处于稳定状态的。 - This paper , in the light of the special geological environment and actual project situation of the three gorges reservoir area , puts forward a comprehensive analysis and evaluation system suitable for the stability analysis of the bank landslide of the three gorges reservoir area under the premise of thorough consideration of the water influence on the stability of the bank landslide , and obtains the following achievements in several aspects that have the practical application significance and certain scientific research value : ( 1 ) it is discovered that the water activity is the primary factor of the formation of the new landslide and the revival of the ancient landslide . on the one hand , the rising underwater level reduces the actual stress of landslide ; on the other hand , the long time soaking of the underwater reduces the mechanics intensity of the landslide and the slide belt , both of which reduce directly the landslide stability ; ( 2 ) in view of the special condition of the three gorges reservoir area , this paper analyzes systematically the forces acted on the landslide of the three gorges reservoir area and the force varieties acted on the divided landslide when the water level changes between 175 meters and 145 meters . thus it is more scientific and comprehensive for the analysis of the forces acted on the landslide ; ( 3 ) this paper summaries systematically 10 kinds of typical computation projects by organic combinations of different kinds of situations in the dry season ( nature statue ) , rainy season ( rainstorm or rains for a long time condition ) , with 175m water level in the reservoir , during the earthquake , with the water level of the reservoir adjusted from 175m to 145m and so on , and produces
本文针对长江三峡库区特殊的地质环境与工程实际情况，在充分考虑水对库岸滑体稳定性影响的前提下，提出了一个适用于长江三峡库岸滑坡体稳定性分析的综合分析评价体系，并取得了如下几个方面具有工程实际意义和一定科学研究价值的研究成果： ( 1 )研究结果发现，水的活动是新滑坡形成或古滑坡复活的主要因素，一方面是由于地下水位升高降低了滑坡体的有效应力，另一方面是由于地下水的长期浸泡降低滑体及滑带的力学强度，这两方面的因素均将直接降低滑坡的稳定性； ( 2 )针对三峡库区的特殊条件，系统分析了作用于三峡库区滑坡体上的力系和库水位在175m与145m间变化时滑体条块的受力变化，从而使对作用于滑坡体上的力系分析更科学、更全面； ( 3 )通过对滑体处于旱季(天然状态) 、雨季(暴雨或长期降雨状态) 、 175m库水位、地震以及库水位由175m调节下降至145m等各种不同情况的有机组合，本文系统地归纳总结出了10种典型计算工况，并具体给出了相应的作用荷载的计算方法，使在库区岸坡滑体稳定性分析评价时对计算工况选择及其作用荷载的计算更具规范性； ( 4 )具体运用c + + builder开发了关于滑坡体稳定性综合分析评价系统，使对滑坡体稳定性分析计算更方便、更准确； ( 5 )将上述滑坡体稳定性综合分析评价系统应用于重庆市丰都县名山滑坡稳定性分析的具体事例中，分析结果表明，本文所提出滑坡体稳定性综合分析评价方法对三峡库区的滑坡稳定性分析是实用可行的。 - The new applications of survey are described in the fields of indicating underground advance , seeking out lossed ore deposit , discovering neotype deposit for detecting the gold deposit ; determining productive aquifer for looking for groundwater ; discovering fracturation zone controlling crop out of hot spring for developing the hot spring , and locating the position of ancient rock slide for prospecting the earth slide
