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
本文針對長江三峽庫區特殊的地質環境與工程實際情況，在充分考慮水對庫岸滑體穩定性影響的前提下，提出了一個適用於長江三峽庫岸滑坡體穩定性分析的綜合分析評價體系，並取得了如下幾個方面具有工程實際意義和一定科學研究價值的研究成果： （ 1 ）研究結果發現，水的活動是新滑坡形成或古滑坡復活的主要因素，一方面是由於地下水位升高降低了滑坡體的有效應力，另一方面是由於地下水的長期浸泡降低滑體及滑帶的力學強度，這兩方面的因素均將直接降低滑坡的穩定性； （ 2 ）針對三峽庫區的特殊條件，系統分析了作用於三峽庫區滑坡體上的力系和庫水位在175m與145m間變化時滑體條塊的受力變化，從而使對作用於滑坡體上的力系分析更科學、更全面； （ 3 ）通過對滑體處于旱季（天然狀態） 、雨季（暴雨或長期降雨狀態） 、 175m庫水位、地震以及庫水位由175m調節下降至145m等各種不同情況的有機組合，本文系統地歸納總結出了10種典型計算工況，並具體給出了相應的作用荷載的計算方法，使在庫區岸坡滑體穩定性分析評價時對計算工況選擇及其作用荷載的計算更具規范性； （ 4 ）具體運用c + + builder開發了關于滑坡體穩定性綜合分析評價系統，使對滑坡體穩定性分析計算更方便、更準確； （ 5 ）將上述滑坡體穩定性綜合分析評價系統應用於重慶市豐都縣名山滑坡穩定性分析的具體事例中，分析結果表明，本文所提出滑坡體穩定性綜合分析評價方法對三峽庫區的滑坡穩定性分析是實用可行的。From this point, this study frees from the traditional limit which focuses on adult plant only, putting the stress on studying the dynamic adaptive change of the structure and function of the sprout
本研究以此為出發點，擺脫傳統的對旱生植物成株研究的局限，側重研究旱生植物自種子萌發開始后約60天內的幼苗結構、功能的動態適應變化。
