破片巖 的英文怎麼說
中文拼音 [pòpiānyán]
破片巖
英文
sparagmite-
Stability of rock slopes is generally controlled by the structure of rock masses, especially the soft structure surfaces. analysis of rock mass structures is a key to establish geological models and numerical simulation and a foundation to assess the stability of rock slopes. the weak structure surfaces are mainly bedding planes, faults, joints, schistosity plane and contact zones of intrusive bodies. since they are different in genesis and scale, the rock masses are different in features and mechanical intensities. based on the combination of rock structure bodies, 15 basic modes of deformation and failure of rock slope are systematically summarized. the deformation and failure of rock masses actually result from the recombination and rearrangement of these rock bodies. there are 11 types of rock mass structures and various deformation and failure of bank slopes are present in the reservoir area of the three gorge project
巖體結構，特別是軟弱結構面對基巖斜坡變形與破壞具有顯著的控製作用，巖體結構模式分析是建立斜坡地質模型和數學模型的關鍵和評價斜坡穩定性的基礎。巖層層面斷裂構造節理裂隙片理與劈理以及侵入體和圍巖的接觸帶等是控制基巖斜坡穩定的軟弱結構面，這些成因不同大小不一的結構面將巖體分割成性質各異力學強度不均的各種巖體結構體，構成了15種基巖斜坡變形破壞的巖體結構基本模式。不同結構體的重新組合與排列是斜坡失穩的內在原因。Preliminary study of overburden breakdown law with full mechanised top coal caving mining under thick and hard gneiss
硬厚片麻巖下綜放採煤覆巖破壞規律初探Descending into the grotto, he lifted the stone, filled his pockets with gems, put the box together as well and securely as he could, sprinkled fresh sand over the spot from which it had been taken, and then carefully trod down the earth to give it everywhere a uniform appearance ; then, quitting the grotto, he replaced the stone, heaping on it broken masses of rocks and rough fragments of crumbling granite, filling the interstices with earth, into which he deftly inserted rapidly growing plants, such as the wild myrtle and flowering thorn, then carefully watering these new plantations, he scrupulously effaced every trace of footsteps, leaving the approach to the cavern as savage - looking and untrodden as he had found it
然後，走出洞來，把那塊石頭蓋回原處，在上面堆了些破碎的巖石和大塊的花崗石碎片，又用泥土填滿石縫，移了幾棵香桃木和荊棘花種植在這些石縫里，並給這些新移種的植物澆些水，使它們看起來象是很久以來就生長在這兒的一樣，然後擦去四周的腳印，焦急地等待他的同伴回來。他並不想整天地去望著那些黃金和鉆石，或留在基督山島上，象一條似的守護著那些沉在地下的寶藏。The supporting mechanism of pre - stress anchor is given in following sentences in this paragraph : make full use of sectional stability, put - up steel - net shot concrete to the stratified earth as the trench is being excavated, and by this means, the little liding of soil layers and small broken slumps of rock slopes can be avoided
預應力錨板的支護機理：充分利用巖土層自身或預處理的局部的穩定性，隨基坑開挖分層掛鋼筋網噴射砼，以避免土層幫片及巖石邊坡小的節理破碎滑塌，並把土壓力傳給錨板，由錨桿集中受力，通過錨桿的錨固力平衡土壓力。Through the statistic and analysis of rock core crack, sonic wave velocity test, microcosmic structure of core slice observation by electron microscope, core strength test to the sampled damaged slope rock mass, it indicates that the damage degree of smooth blasting to slope rock mass has no obvious relation with blasting scale but with the line density of explosive filling and the strength of the rock in damaged area decreases evidently
通過受損邊坡巖體取樣巖芯裂隙的統計分析、聲波速度測試、巖芯切片微觀結構的電鏡觀察及巖芯的強度試驗，發現光面爆破對邊坡巖體的損傷程度與爆破規模無明顯關系，而與光爆孔的線裝藥密度有關，損傷區巖石的強度明顯降低。The experiments of 9 pieces of confined shale brick masonry walls subjected to low - cyclic reversed horizontal load were carried out, and the failure characteristics, seismic behavior and lateral - resisting bearing capacity of this kind of walls were studied
摘要通過9片約束頁巖磚砌體墻的低周反復水平荷載試驗，研究了約束頁巖磚砌體墻的破壞特徵、抗震性能和抗震受剪承載力計算公式。Being calculated, the frame beam - on - foundation may be disconnected to two single beams. on the pulling anchor - cable step, the internal force of single beam - on - foundation can be calculated by winkler hypothesis in the case of weak rock mass and infinite half elastic foundation hypothesis in the case of stratums that are of some elastic characteristics. the internal force of frame beam - on - foundat
在張拉階段，對于單片型地梁，可以採用溫克爾假定計算破碎軟弱巖體上的地梁內力；有較好彈性性質的地層，可按彈性半無限體地基計算地梁內力；對于框架型地梁，可按溫克爾地基模型計算其各單片梁的內力。分享友人
