选择合理施工工艺参数采用沉降差法控制石方路基压实质量

Choose Reasonable Construction Process Parameters Controlling the Compaction Quality of Shifang Subgrade by Settlement Difference Method

目前国内填石路基检测压实质量常采用干密度、沉降差、面波等单一方法进行质量检测,这些方法均存在一些不足。我们知道路堤压实质量与压路机的压实功率、碾压速度、压实遍数、铺筑厚度、填料粒径、填料强度等施工工艺参数有关。如果采用沉降差法检测压实质量并同时对施工工艺参数进行控制,能够有效地保证填石路堤的压实质量。

at present,the quality of the compaction quality of the domestic filling stone roadbed is often used to detect the quality of the single method,such as dry density,differential settlement and surface wave,etc.,which have some shortcomings.We know that the compaction quality of the embankment is related to the compaction power of the roller,the compaction speed,the compaction,the thickness of the pavement,the filling particle size and the filling strength.If the compaction quality is detected by the settlement difference method and the construction process parameters are controlled simultaneously,the compaction quality of the filling stone embankment can be ensured effectively.
