Depending on how the ground surface is denuded, the feature of the current crustal stress field and rock stress environment can be calculated analyzing the result in this paper : by analyzing the recovering feature of the elastic deformation of the rockmass in unload - stage under various pressures, it has been found there is close relationship between the recovering degree of the elastic deformation of the rockmass and the unloading degree of the pressure the direction of the major principal stress in the crustal stress field is not consistent with the direction of the crushing stress regional tectonics borne during the last tectonic movement. the evolving degree of the regional geomorphology evidently affects the current crustal stress field, which changes from the self - weight stress field to the horizontal stress field, with the changing of the eroding degree of the regional geomorphology ranging from valley area to hilly country to flat country. in valley area, where there is two stress belts, the bankslope s tress belt and the self - weight stress belt within the mountain. the direction of the major principal stress is nearly parallel to the ground surface and inclines towards the valley in the bankslope stress belt. it is nearly vertical in the self - weight stress belt
通過本文的研究成果，根據區域性地貌的演化特徵，我們可以大致地對現今地應力場進行判斷：在分級卸荷條件下，巖體中彈性變形的恢復具有明顯的規律性，這種規律對于研究地應力場的演變是有幫助的；地應力場中最大主應力方向與區域構造形跡在最近的構造運動中所受區域性擠壓應力的方向無明顯的對應性；區域性地貌形態的演化程度對現今地應力場的特徵具明顯的影響，隨著區域性地貌侵蝕程度由峽谷區、丘陵區、平原區的變化，現今地應力場特徵由自重應力場、水平應力場為主含少量自重應力場特徵向水平應力場的規律變化；在峽谷區，山體中具有兩個應力帶：自重應力帶和卸荷應力帶，最大主應力方向在卸荷應力帶中近平行於坡面並傾向于河谷、在自重應力帶中近於直立；根據原始地面遭剝蝕的程度，可以大致地估算最大主應力和中間主應力的量值和方向；在丘陵區和平原區，最大主應力的方向近於水平，並與附近區域性侵蝕盆地和河流的展布方向基本平行，根據原始地面遭剝蝕的程度，可以大致估算其最大主應力的量值；根據區域性地貌形態的特徵來分析工程區的現今地應力場特徵，並進而大致了解巖石的應力環境，這種分析方法得出的結論與許多實際的地應力測試成果基本一致，對于大型水電工程地下廠房和壓力隧洞的設計是有所幫助的。 -
Measurements demonstrate that the regional tectonic setting apparently does not control the features of the current crustal stress field, the direction of the major principal stress in the current crustal stress field is not consistent with the direction of the crushing stress regional tectonics borne during the last tectonic movement
許多地應力場的實測資料表明：區域性地質構造特徵對現今地應力場並無明顯的控制性，現今地應力場中最大主應力的方向與挽近期區域性擠壓應力方向並非具一一對應的關系。 -
Based on the characteristics of the quaternary tectonic activities of babaoshan - huangzhuang - gaoliying fault and the regional principal compressional stress direction and regional tectonic activities derived from the recent cross - fault displacement observation data in the capital area, we have analyzed the relationship between the fault movements at 7 cross - fault observation sites on the babaoshan - huangzhuang - gaoliying fault and the seismicity, conclude that the capital and adjacent area is soon to enter upon the next active period of earthquakes
摘要根據八寶山黃莊高麗營斷裂第四紀地質構造活動特徵和利用首都圈地區跨斷層位移最新的觀測資料求得的北京地區區域主壓應力方向和區域構造活動特徵，分析了八寶山黃莊高麗營斷裂上7處跨斷層位移測點的斷層活動與地震活動的關系，得出了首都圈及鄰近地區即將進入下一個地震活躍期的結論。 -
The geo - dynamic division method, based on tectonic plate structure theory, takes the local geology structure as its principal research object
摘要介紹了地質動力區劃方法及其在開灤礦區的應用。 -
Research shows that four factors have great influence on the formation of complex rock mass. first, rock mass subjected six times of tectonic movement during long period of geo - history, each tectonic movement produced fractures and associated joints corresponding to the orientation of maximum principal stress and deteriorated the properties of fractures formed at former period ( s ). second, down - cutting of langcangjiang river produced unloading fractures
採用了四種巖體質量分級評價方案對研究區巖體質量進行了研究，這四種方案包括：工程巖體分級標準（ gb50218 - 94 ） 、水利水電圍巖工程地質分類（ gb50267 ? 99 ） 、巖體rmr分類（ bieniawski ， 1973 ） 、巖體質量指數z分級（小灣， 1995 ） 。
