谷底階地
英文
bed terrace-
A large amount of data of the latest regional geoglogy and the latest correlation data of layers and rock formation have been quoted, and a description of distribution of crystalline basement, formation, evolution as well as the distribution characteristic of the fracture belt of ordos basin have been made in this paper, and the paper also pointed out that the g - layer which lies between the base of the basin and tg reflector, is the extension of basinward of guandaokou of jixian system. the layer of changcheng system and jixian system, which had been divided before, can be correlated with the exposed huangqikou group and wangquankou group in helan mountain, and divided into qingbaikou system. so, the paper denied the viewpoint of the existence of aulacogen in hutuo period and middle proterozoic in this basin
文中引用了大量最新的區域地質資料和最新的地層、巖系劃分對比資料，對鄂爾多斯盆地結晶基底的巖系分佈、形成、演化以及斷裂的展布特徵進行了描繪，並指出盆地基底與tg反射層之間的g層是薊縣系官道口群向盆地的延伸，盆地中原劃分的長城系、薊縣系地層可以和賀蘭山出露的黃旗口組、王全口組對比，亦劃歸青白口系，從而否定了鄂爾多斯盆地存在滹沱期坳拉谷和盆地中有中元古坳拉谷發育階段的看法。( 6 ) conclusion was obtained by the analyzing the mechanics environment and the stability of the lanslide on the right bank after the dam built : the value of the rock mass stress increased and the tensile stress region obviously reduced, the direction of the principal stress was unchangeable the dam and the landslide were stable under the dangerous condition ( the reservoir and at the same time the earthquake was viii ), but when the water lever suddenly fell and did not think of other force, safe factor evidently reduced, the dam and the landslide will be destroyed under the most dangerous condition ( the water lever suddenly fell and at the same time the earthquake was vi ) ; the stability of the landslide will be destroyed by the horizontal thrust under the most dangerous condition or ; the physical and mechanical parameter will be reduced due to long period filter, the landslide will be destroyed too
（ 6 ）建壩工程荷載條件下河谷巖體力學環境分析及右岸古滑坡體的穩定問題分析得出：建壩后河谷的巖體應力量值明顯增高，同時左岸的張應力區的范圍及量值明顯減小，主應力的方向依然與模型的底邊界垂直；大壩建成后逐漸蓄水階段以及同時考慮本區最強地震力的作用等各種不同的工況條件時，滑坡體及壩體總體上仍處于穩定狀態；水位驟降時，在未考慮其他外力作用的情況時，滑體的安全系數將顯著降低。若考慮水位驟降及本區最大地震力的共同作用，壩體將在滑坡體下滑推力的作用下產生破壞；建壩后水平推力對右岸古滑坡體穩定性的影響分析可以看出，在最危險的工況條件下，壩體及滑坡體也將處于臨界狀態；在長期滲透變形的作用下，由於滑帶的物理力學參數的降低而有可能導致壩體失穩破壞。There in the middle of the moonlit valley below them stood the " ha nted " house, utterly isolated, its fences gone long ago, rank weeds smothering the very doorsteps, the chimney crumbled to ruin, the window - sashes vacant, a corner of the roof caved in
在他們下面的山谷中間，那間「鬼屋」 ，孤零零地立在月光底下，圍墻早就沒有了，遍地雜草叢生，臺階半掩，煙囪傾坍，窗框空空蕩蕩，屋頂一個犄角也塌掉了。
