piping erosion 中文意思是什麼
piping erosion
解釋
管涌侵蝕-
The major causes for dyke breaches are the strong permeability of soil at the dyke breaches, resulting in infiltration or piping firstly, and nonuniform settlement on water side and land side of the dyke due to a long - term soakage of the dyke, further leading to cracking and erosion, and finally breaching of the dyke
潰口發生的主要原因是潰口處土壤組成透水性強，先發生散浸或管涌等險情，加上浸滄時間長，迎水面和背水面堤身沉陷不均勻，導致裂縫出現和沖刷的加劇也都促成潰口發生。 -
Thus, the piping - induced failure of two - layer foundation was verified as that ： mass flow firstly appears in the upper weakly permeable layer, and then underground erosion and scouring gradually occur from downstream to upstream between the serviously and weakly permeable layers
從而驗證了二元結構堤基的滲透破壞模式為：首先在上層弱透水層中發生流土，然後在強、弱透水層之間發生自下游向上游的逐步潛蝕沖刷。 -
In order to exhibit the application of the method of porous media macroscopical geometric classification and minimum energy dissipation, the combination system between one - dimension pipeline media and three - dimension block media is tried to simulate the destroying and developing process of soil piping erosion
為了進一步展示多孔介質宏觀幾何分類方法及最小能量耗散原理的應用，文中還嘗試採用具有一維性質的管道介質與具有三維性質的塊體介質組合體系進行了土體管涌破壞發展過程的模擬。
