Chagan sag is a secondary tectonic unit in chagandelesu depression, northeastern yingen - eji ' naqi basin, and the basement of the basin is a paleozoic fold belt of continental margin or island arc at the connection region of north china plate * tarim plate and kazakstan plate, with the character of erogenic belt. in working area and its adjacent area, the forming tectonic setting of indosinian intrusion was that orogenic belt pressed strongly, intracontinental subduction ; that of early yanshan movement epoch was the stress field transferred from compression to extension meanwhile the incrassate crust of orogenic zone turned to extensional collapse ; and that of early cretaceous volcanics was that the area structure extensional collapse further more during the post period of orogenic phase
查干凹陷屬于銀根?額濟納旗盆地東北端查干德勒蘇坳陷內的一個次級構造單元，其盆地基底為古生代時期華北板塊、哈薩克斯坦板塊和塔里木板塊交接部位形成的陸緣或島弧褶皺帶，具有古生代造山帶的性質。研究區及鄰區印支期侵入巖形成於造山帶強烈擠壓陸內俯沖的構造環境；燕山早期侵入巖形成於由擠壓轉向拉伸、造山帶的增厚陸殼開始發生伸展垮塌的構造環境；早白堊世火山巖形成於造山期后進一步發生伸展垮塌的區域構造環境。 -
Based on the simplified structure of rock mass, flac ( superscript 3d ) numerical modeling technique is used to systematically analyze the distribution features of the secondary stress field, strain field and plastic zones in the surrounding rock mass of the underground cavities after the excavation
摘要在巖體結構模型概化的基礎上，採用flac （上標3d ）數值分析方法，系統研究了瀾滄江某大型水電站大跨度、高邊墻地下洞室群開挖完成後圍巖的二次應力場、變形場和塑性破壞區的變化特徵。 -
Abstract : taking the underground powerhouse in a huge hydropower station as an example, the authors studied distribution pattern of the secondary stress field of surrounding rock mass with nonlinear finite element method of the large - spaned underground powerhouse with high side wall and evaluated the stability of surrounding rocks
文摘:以某大型水利工程擬建地下廠房為典型實例，應用二維非線性有限元分析方法，研究大跨度、高邊墻地下廠房區二次應力場分佈規律，並評價圍巖的穩定性。 -
By fem, the numerical simulation was carried out according to such models, many important hemodynamic variables, such as the tempo - spatial velocity field at every cross section of the artery, the pressure distribution, the secondary flow and the wss ( wall shear stress ) at the specific areas were obtained, which will help understand the biomechanics of coronary atherosclerosis furtherly. many investigators studied the stenotic artery by means of 2 dimensional models, which can only simulate the planar pulsatile waves and got, to some extent, some general results of the blood flow without considering the secondary flow and the reality of physiological conditions
本文的著眼點和研究的目的在於，希望利用在血流動力學方面的研究優勢，用有限元方法對動脈粥樣硬化的血流動力學問題進行數值模擬，研究動脈粥樣硬化在生成和發展過程中的血流動力學、血管壁生理及生物力學性能的變化規律，以及這兩種變化規律之間的相互作用與動脈粥樣硬化的發生和發展的關系，通過大量算例的對比分析，以期在這方面作些基礎而有實際價值的工作。
