| 摘 要： | 结合银川绕城高速西北段非典型软弱土路基处治工程,利用现场监测的方法对非典型软弱土路基的处治措施及沉降规律进行了研究.结果表明:该软弱土压缩性较高、承载力低、渗透性差,路堤施工前必须对其进行预处理;换填砂砾垫层、袋装砂井等载预压、挤密碎石桩是处治该种软弱土路基的有效措施;该软弱路基处理设计合理、施工得当,其经验可供同类工程参考和借鉴.

| Abstract: | Through a subgrade treatment engineering example,lacustrine soft soil treatment method and settlement rules of Yinchuan city ring road were studied on the basis of the field monitoring.The results showed that the compression coefficient of the lacustrine soft soil is big,its bearing capacity is low,and it has a poor permeability,the soft soil must be treated before the construction of subgrade.Sand-gravel cushion,bag sand well and broken stone compaction pile are some effective methods to treat this lacustr... |
