滑坡和巖質(zhì)邊坡的變形外文翻譯(完整版)
【正文】 ined shafte and tunnel section and a stell lined section where the rock cover is insufficient to contain the internal pressure in the tunnel. In addition to the construction of this replascement conduit to reroute the water away from the and potetially unstable part of the slope, a prehensive displacement and water pressure montioring system has been installed and is being montiored by BC Hydro. 滑坡和巖質(zhì)邊坡的變形 滑坡是巖石，沉積物，土體在重力作用下沿斜面項(xiàng)下的運(yùn)動(dòng)，它不僅包括其他因素如沖刷，侵蝕，風(fēng)，冰的作用等。這些由陡峭跌落破壞的散散組粒碎屑物越過滑坡并在斜坡底形成碎石堆或巖屑堆。運(yùn)動(dòng)物質(zhì)可能保持半粘結(jié)狀態(tài) 或發(fā)生參合和混合。發(fā)電是由 Wahleach 湖和與Frasere河相鄰的地面發(fā)電站之間 620米水頭差發(fā)生的。 邊坡的破腳埋藏在崩積物和 2 條小溪形成的扇形沉積物下，小溪切割 Fraser 山谷斜坡，并形成一個(gè)山嘴，斜井布置在其中。 對(duì)排水洞調(diào)查發(fā)現(xiàn)，在距離斜井交叉處 55米，上游隧洞鋼襯中又寬 150mm的環(huán)形張裂縫。 。隨后調(diào)查發(fā)現(xiàn)，在 1989到 1990年，大約2020 萬立方米的巖石向斜坡下移動(dòng)，達(dá)到每年有幾厘米，現(xiàn)在仍在蠕動(dòng)。生長在溝槽的大樹表明這些移動(dòng)至少已有幾百年。與水平方向成 48 度夾角的混泥土外殼鋼襯砌斜井，接著是一條長 300米下游隧道和一條 485米地表壓力鋼管輸送到發(fā)電廠外。有的土顆粒只是簡單的向山坡下滑動(dòng)，動(dòng)物挖洞穴推出土體向下移動(dòng)，或者顆粒只是簡單的像坡下滾動(dòng)，因凍融使顆粒緩慢向下移動(dòng)。從坡體上移動(dòng)的碎屑 可能會(huì)移動(dòng) 1 米到 1000米。Landslides and Deformation of Rock Slopes Landslide is the downslope movement of rock,sediment,and soil under the influence of gravity without the aid of the other agents of erosion such as fiowing water,wide,or ice. Landslide debris are transported off a slope within a matter of seconds or minutes to the imperceptible slow creep of individual particles down a gradual types of movements may be triggered by the vibrations from earthquakes or the mechanical pushing or heaving of particles downslope,or they may occur s
