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。Along with the development of power system, more and more generators and ehv transmission systems are put into operation. there come many new situations, such as the lengthening transmission distance, the heavier load, the increasing transient elements during the transient process. these new conditions influence the correct working of relay protections
