The studies of plane heterogeneity are as follows : the text counts the parameters of the sandlayers " geometric shape of different sedimentous microfacies ; speculates the conditions of lateral communication by sandstone density according to the method brought forward by j. r. l. allen ; gets a group of parameters including the reservoir thickness, porosity and coefficient of permeability by using kriging method according to the data of logging results ; makes certain the direction of coefficient of permeability with variation function by modeling globosity function ; divides the sandlayers into five types by using the method of flowing cell based on three parameters, that is x h, kxh and h / h, and accounts the favorable region. on the base of above - mentioned studies, the text evaluates the heterogeneity of sandlayers and gives the resolutions to these problems to serve the development of the field
Allen ）等人提出的統計方法，用垂向上砂體密度的界限來推測砂體側向連通情況；根據每口井的測井解釋資料，利用克里金插值法對外間進行插值，得到了一組反映儲層特徵在平面上變化的參數，包括儲層厚度分佈、孔隙度以及滲透率，並且成圖；利用變差函數法，通過球狀函數模擬，確定儲層優勢滲透率方向：根據流動單元法，以儲能系數、容積系數以及凈毛厚度比三個參數為依據，通過聚類分析方法進行流動單元劃分，並且按照參數特徵將其分為五類，統計各砂層有利流動單元區塊。 -
The condition of water pressure acting on the both sides of cement - soil retaining wall is researched by computing the seepage field around the wall. it is illustrated that the coefficient of water pressure, which isn ' t constant along the height, is affected seriously by some factors, e. g., the distribution and relative hydraulic permeability of the soil beside the wall, the hydraulic permeability of its foundation, and the buried depth of the impervious layer. as a whole, the lateral pressure acting on the wall based on seepage is always smaller than that without regard to seepage in the non - excavated zone. moreover, the pressure based on seepage is greater than that without regard to seepage in the excavated zone if the coefficient of passive pressure is smaller than 1. 176. this case is of great advantage to the stability of the wall
通過計算水泥土擋土墻周圍的滲流場，研究了墻側水壓力的變化規律.結果表明：水壓力系數沿高程並非常數，且受到墻側土層分佈及其相對透水性、墻基土的透水性和下臥不透水層埋深等因素的嚴重影響.總體來說，考慮滲流時墻后的側壓力總小於不考慮滲流時的相應值，且當墻前的被動土壓力系數較小時，考慮滲流時該側的側壓力則大於不考慮滲流時的相應值，因此，這種情況有利於擋土墻的穩定
