| 摘 要： | 对于黄土这种具有特殊结构和化学组成的物质,遇水后其结构将发生显著变化,在已有孔洞的情况下,孔洞会随着水的流速和接触面积的变化发生不同程度的变化。模拟水对黄土的溶蚀作用过程,自制模型,测试出水的流速和接触面积与黄土溶蚀量成一定的函数关系变化,进一步得出流速比接触面积的影响更加显著。

| Abstract: | The loess has a special structure and chemical composition,its structure will change obviously when it meets water.Under the condition of the available hole,the aperture's dimension will change differently as the variation of the flow velocity and contact area of water.By simulating the corrosive action of water and making the model,it is known by tests that the flow velocity and contact area of water are related to the corrosive capacity of loess by a definite function relationship and the contribution of ... |
