  • On the basis of the theory and knowledge of many learning branches such as fractal geometric , the percolation mechanics , the reservoir engineering , mathematic and physic method , numeric analysis method , compute graphic procession method , software engineering analysis method and so on , this thesis based on the developed research work , concludes the following a few facets to the unsteady seepage flow mathematical models in the pressure - sensitive deformable double media fractal reservoir . fractal geometric theory and method are good approximations to describe the complicity and we can more easily analyze all kinds of the pressure - sensitive deformable double media fractal complex reservoir relatively than others
    本文綜合運(yùn)用分形幾何理論,滲流力學(xué)理論,油藏工程方法,數(shù)學(xué)物理方法,數(shù)值計算,計算機(jī)圖形處理技術(shù),軟件工程的分析方法等方面的理論知識和應(yīng)用技術(shù),在已有研究成果的基礎(chǔ)上,對分形油藏作了以下幾方面的研究:一-一- -絲竺絲型進(jìn)些絲燮竺鯉絲竺塑望絲些些竺色? ( l )以m厄仃en一root模型為基礎(chǔ),引入分形參數(shù)d了、 0和壓縮系數(shù)。
  • Some key subjects of numeric analysis were discussed such as : selecting principles of constitutive equations of soft clay , the equivalent theory of vertical drains ground , the definition of load step , the determination of vertical drains as well as the treatment methods of the decline of groundwater level , sealing wall and nearby water source
    著重論述了真空預(yù)壓加固地基數(shù)值分析中對土體本構(gòu)方程的選擇、砂井地基等效轉(zhuǎn)換、分析荷載步的確定、豎向排水體的界定、地下水下降的處理、密封帷幕的處理、附近補(bǔ)充水源的處理等問題。
  • ( 三 ) under the dynamic load of the explosion , the numeric analysis has been done and achieve the rule as follow : ( 1 ) when the frequency of vibration is 0 . 3hz , the acceleration of the slopes top gets the maximum ; so 0 . 3hz is believed the natural frequency of the slope as a whole ; ( 2 ) the vibration of explosion can been magnified because of the condition of the landform , when the relative altitude is up to 45m , the acceleration of horizon gets the maximum ; when the relative altitude is up to 100m , the absolute value of acceleration and the deformation of horizon is larger than that in the bottom of the slope ; ( 3 ) in the period of forced vibration , at the top of the slope , the acceleration of horizon become larger and larger ; at the middle part of the slope , it becomes smaller ; ( 4 ) when the explosion velocity of is much little , the shallow part destruction is the primary deformation of the slope
    (三)采用模態(tài)疊加法針對爆破動力作用,進(jìn)行邊坡的動力響應(yīng)分析,得出了以下結(jié)論: ( 1 )振動頻率為0 . 3hz時,坡面頂部水平向加速度峰值最大;綜合考慮,可認(rèn)為該邊坡的自振頻率為0 . 3hz左右; ( 2 )地形對爆破地振動存在放大作用,研究剖面的坡面,水平向加速度及位移在地形相對高差45米左右最大,而后隨相對高差的增高而減小,相對高差為100米時,水平向位移及加速度絕對值均大于坡腳; ( 3 )強(qiáng)迫振動段,水平向加速度值隨時間變化的規(guī)律為:坡頂節(jié)點總的變化趨勢是越來越大,而坡體中部節(jié)點的變化趨勢是越來越??; ( 4 )當(dāng)爆破振速較小時,變形破壞的形式表現(xiàn)為坡頂表面滑塌型。
