  1. Aerodynamic roughness of cultivated soil and its influence on soil erosion by wind in a wind tunnel

    耕作土壤表面的空氣動力學粗糙度及其對土壤風蝕的影響
  2. Erosion damage decreases rock load area, after defining damage variable, the damage stress in rock can be calculated by the method bring forward by lemaitre conveniently. for surrounding rock of a deep buried tunnel under the condition of drained, its seepage character is not only controlled by the high stress in rock, but also influenced by the development of erosion damage. in the whole course of rock " s deformation and failure, its seepage character decreases with the increment of stress in elastic stage, while " increases with the development of failure

    巖樣中全應力?應變三軸滲透試驗過程中的典型表現為隨著應力的增加，巖體內的空隙和裂紋受載閉合，滲透性降低，應力達到一定閾西南交通大學鷹士研究生學位論文第11頁值后，巖體內部裂紋發生擴展和歸並，滲透性增強；同樣，地下水的動、靜壓力作用對裂紋的擴展和歸並也起著促進作用。
  3. Stress decreases rock seepage character in elastic stage, while erosion damage increases it. under some conditions, the influence of stress to seepage may be shielded by erosion damage. obtaining the distribution of seepage field, tunnel external water pressure can be calculated in two ways : 1

    高應力使裂隙閉合，一般是降低巖體的滲透性，而水化水力損傷則增加巖體滲透性，在腐蝕損傷發育到一定階段，應力對滲透性的這種影響則可能會被屏蔽。
  4. Therefore, this article has carried on the following work : 1. designed and made a movable wind erosion tunnel drove by tractor firstly in our country. the wind speed range of the tunnel is from 2 m / s to 28 m / s and the speed can be adjusted continuously

    研製了我國第一座使用拖拉機為動力的移動式風蝕風洞，風洞風速為2 28m s ，且連續可調，風洞總長11m ，實驗段長6m ，為無底矩形截面， 1 . 0m高、 0 . 8m寬。
  5. Wind tunnel experiment on the impacts of polyacrylamide on wind erosion of loosen soil materials

    防治鬆散擾動沙土風蝕效果的風洞試驗研究
  6. So, it is significant from present and long - term benefits to design and make movable wind erosion tunnel, and to apply it as a tool to carry out research on protective cultivation, diminution of soil wind erosion, reduction through conservation tillage

    因此，設計和製作移動式風蝕風洞，用風洞作為有力的工具，開展保護性耕作減少土壤風蝕，防治沙塵暴的研究就具有重要的現實意義和長遠意義。為此本文進行了下列工作： 1
  7. The erosion effect damage variable can be defined in many ways, while the one defined in wave velocity by author is more appropriate for deep buried tunnel surrounding rock. for the evolution of hydraulic damage under complex mechanics environment, the extension of branch fracture means the initiation of evolution, and the hydraulic damage evolution equation can be deduced by the method of fracture mechanics

    水化-水力損傷巖體中損傷變量可以採用多種方法定義，在分析隧道巖體內部結構時，彈性波速是比較容易量測的巖體物理量，可用其來定義巖體中的腐蝕損傷變量。
