| 摘 要： | 采用模拟机械压实土壤的方法进行5种载荷的土壤压实试验,测定不同深度处土壤水分的值,并与压前土壤水分进行了对比。结果表明:增大载荷和增加压实次数都会使土壤水分损失,最大可使水分损失23.1%;压实对一定的土壤层(25cm以内)的水分损失影响显著,并且模拟载荷在200kg以内对土壤的水分损失影响比较大。

| Abstract: | Moisture values at different depths of soil are measured through 5 kinds of load soil compaction test using the method of simulation of mechanical and were compared with that before compacted.The result shows: increasing loads or the number of the compaction will cause the loss of soil moisture,up to 23.1% at most;compaction affects the moisture loss of the specific soil layer(25cm or less) significantly,and the soil moisture losses are influenced prominently by the simulation loads under the 200kg. |
