| 摘 要： | 在沙壤土上对常用的3种载荷进行了压实试验,测出了土壤压实前后的参数.结果表明:在0～100mm土壤深度处,载荷大于3000kg时,使容重增大较剧烈;载荷大于2000kg时,使湿度损失较严重,4400kg时损失了20%,使坚实度的增量增加剧烈,4400kg时增加了59%,而使最大坚实度增加了114%,并且大载荷对深层(大... |

| Abstract: | Field tests were carried out using 3 commonly different loads on ShaRangTu in order to measure the compaction before and after the parameters.The result shows:In 0-100mm soil depth place,more than 3000kg load that bulk density increases more intense,more than 2000kg load,make humidity loss more serious,4400kg loss 20%,make the hardness of incremental increase significantly,4400kg up 59%,and make the largest hardness increase 114%;and the larger load of a deep(more than 100mm)soil hardness significant effects. |
