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。

The one side of some hillside limestone quarry is high bedded rock slope, so the stability of this slope is a primary problem of mine safety, and the earthquake effect caused by blasting is one of great factors influencing slope stability

摘要某山坡露天石灰石礦的一側為順層巖質高邊坡，其穩定性是礦山安全的主要問題，而影響邊坡穩定的主要因素之一是爆破地震效應。

Some stiffness matrices of special elements such as rubber bearings and components with field are derived from primary - secondary and inverse transform in structural matrix analysis. then, seismic response analytical models and non - isolated continuous rigid frame bridges are set up, while considering the interaction of soil - pile - structure and traveling wave effect simultaneously. finally, the seismic time history response of the two models is calculated by means of the finite element method, and the results show that the isolated bridge posses powerful earthquake resistance

首先論述了公路大跨徑橋梁的地震反應分析方法，其中包括樁-土-結構相互作用、行波效應等因素對結構物的影響；其次，利用結構矩陣分析中的主從變換和逆步變換，推演了幾個特殊單元的剛度矩陣，包括橡膠隔震層單元和帶剛域構件單元；最後，考慮樁-土-結構相互作用和行波效應的結合，分別建立隔震與非隔震連續剛構橋地震反應分析模型，通過有限元法對兩種結構進行時程分析，結果表明：隔震層上部結構的地震加速度反應、位移反應均明顯減小，這說明隔震的連續剛構橋具有很好的抗震能力。

Primary earthquake disaster

地震直接造成的災害

In the end, the paper sums up the calculation results, and reviews the whole performance of this type of structures under earthquake actions. except that, it reviews the structures " security about the translation - and - torsion coupling response under the fortification and rare seismic actions, and gives a primary evaluation ; it also discusses some characters of the structures " three - dimensional nonlinear response of torsion under earthquakes
