造成這種影響的主要原因在於細小的硅粒比較容易協同基體塑性變形和被刀具壓入切屑和已加工表面,而粗大的硅塊往往發生解理破碎、脫落和位移,直接與刀具發生強烈摩擦並使已加工表面存留許多缺陷。These landslides go with fluidization peculiarity different degree in course of their motion, and their speed and distance increase several times because of the fiuidization, thereby the disaster area greatly broaden. on the base of above, the paper studies systematically the fluidization of large high - speed rockslides in all its aspects : analyzed the aerodynamic effect in the short - range on the base of the wind turmel experiment, studied the effect of falling into pieces when landslides collides mountain ; studied the accelerating effect through high - speed collide experiment of landslides model ; and the paper reappear the overall process including set - out, collide in the short range, debris flow in the long - range of touzhai large landslide via distinct element method ( dem ), studied the flow law and equation of different type of debris flow resulted from large landslide. as a sample to apply, the paper analyzed fluidization mechanism of touzhai landslide
基於這一點,本文對大型高速巖質滑坡的流體化現象進行了全面而系統的研究:通過風洞模型實驗,研究了大型高速滑坡凌空飛行階段的空氣動力學效應,研究了飛行中滑坡巖體在與途中不動山體發塵碰撞時的解體破碎效應,通過滑坡巖體高速碰撞模型實驗研究了滑坡巖體解體破碎後部分巖體的加速運動效應,並應用離散單元法再現了雲南頭寨溝大型滑坡啟動高速、近程碰撞、遠程碎屑流運動的全過程,研究了巖體解體破碎后形成不同類型碎屑流的運動規律及運動方程,並對頭寨滑坡流體化運動機理進行了實例分析,取得了以下主要結論和成果: ( 1 )對于大型高速滑坡,大多在啟程活動階段已獲得了高速,這使得這類滑坡在其離開剪出口之後以凌空飛行的形式向前運動,在其飛行過程中,滑坡巖體與空氣強烈作用,並產生空氣動力學效應,滑坡巖體在因碰撞而產生的解體破碎效應及部分巖體的加速運動效應的作用下,在遠程活動階段,以高速碎屑流的形式向前運動。This is the direct reason of bad reservoir property of sandstone, especially lower permeability. the influence and control factors of reservoirs include : deposition, diagenesis and tectogenesis. the deposition is the basic factor, it control the shape and distribution of sand body, and influence the type and the intensity of the diagenesis ; the diagenesis is the key factor, it control the process of pore evolvement, so the diagenesis control the sandstone ' s storage space and reservoir quality directly ; the fracture of the tectogenesis formation could improve the porosity and permeability of sandstone
其中沉積作用是基礎,控制了儲集砂體的形態特徵和分佈范圍,同時由於不同沉積類型砂體在碎屑成分組成、泥質含量、顆粒粒度、砂體厚度、砂體內部的非均質性、孔隙介質的物理化學性質等方面不盡相同,從而也影響著砂巖所經歷的成巖作用路徑、類型和強度,因此沉積作用是控制儲層發育的主導因素;成巖作用是關鍵,直接決定了砂巖的孔隙演化過程,從而決定了儲層內部儲集空間特徵和儲集性能;而構造作用形成的裂縫對改善砂巖的儲滲性能具有一定作用。These characteristics are different from those in medium to shallow layers, and they are the main mineralogic controlling factors resulting in the sensitivity of deep clastic reservoirs
這些特徵不同於中淺層,是造成深層碎屑巖儲層敏感性的主要礦物學控制因素。分享友人
