卸載巖體 的英文怎麼說
中文拼音 [xièzǎiyántǐ]
卸載巖體
英文
relaxed rock-
After researching the loads on dangerous rock synthetically, the author points out the development and collapse mechanism of dangerous rock : the geology foundations that forms dangerous rock are the constructional surfaces such as tectonic fracture 、 relief fissure, soft interlayer etc. the developing of dangerous rock is due to release of in - situ stress in rock 、 aeolation 、 water erosion and root flerry. the main loads leading to collapse of dangerous rock are gravity, water pressure and earthquake force
在綜合研究危巖上的各種作用之後，本文提出了危巖的形成和破壞機理：硬質巖體中構造裂隙、卸荷裂隙、及各種軟弱夾層，結構面的的存在是危巖形成的地質基礎；地應力卸荷、風化、流水侵蝕、植物根劈是危巖發育的主要作用；重力、水壓力、地震力是危巖崩塌的主要荷載。At the moment, the basic theory of loading mechanics is always used to search the problem of rock mass failure, but unloading and loading have different stress road and different destruction effect, so there are much difference in destruction mechanics and deformation between unloading and loading mechanics, if loading mechanics is used to study the destruction property of tunnel excavation and its stability, the result which agree to real engineering cannot be obtained
目前一直沿用加載巖體力學方面的基本理論研究失穩問題，但本文認為：由於卸荷與連續加載具有完全不同的應力路徑和破壞效應，在破壞機理、二者引起的巖體的變形和破壞特性方面都有很大的不同，因此用加載力學來研究開挖卸荷破壞的力學特性及其穩定性，這顯然不能得出與實際工程一致的結果。Actual computation proves the said new method is both feasible and practical. rock mass projects are of different engineering mechanical states including loading, unloading, coexistence of loading and unloading, alternation of loading and unloading
6 、巖體工程存在加載、卸荷、加卸載並存和交替加卸載等多種工程力學狀態，邊坡工程宜採用卸荷巖體力學理論研究。Due to the difference in stress paths between the loading and unloading conditions, it is unsuitable to apply mechanical model under loading condition to stability of tunnel excavation
由於巖體在加載和卸載條件下應力路逕的不同，僅採用加載條件下所建立的力學模型來研究隧道的開挖穩定性問題是不適合的。分享友人
