摘要
天然砂砾料是山区河道中丰富的自然资源 ,也是压实后稳定性良好的路基填筑材料 .针对现行规范规定的路基压实度检测方法对砾料路基碾压成型层破坏严重且工作效率低的缺陷 ,通过沉降观测法与灌水法对比试验 ,研究了采用沉降观测法控制天然砾料路基压实度的可靠性 .研究成果对同类路基工程有参考价值 .
Natural gravel is rich natural resources and also better stable compacting roadbed material in the river courses of mountain areas.Being aimed at the defects of grievous destruction to rolled gravel layer and inefficiency of the roadbed compaction test method specified in current code,the comparative tests of the settle observed method and water filling method were carried out.The reliability of using the settle observed method to control the compacting of natural gravel roadbed is studied.It can be used as the important reference for the same kind of roadbed engineering.
