Compaction quality control method for construction of soil-stone mixed filling roadbed
The invention discloses a compaction quality control method for earth-rock mixed filling roadbed construction. The method comprises the following steps: S1, establishing a discrete element model of an earth-rock mixed filling roadbed; s2, particles of different grades are generated in the discrete element model according to the particle size; s3, applying a vibration load to the discrete element model, wherein the size of the vibration load is the same as that of the load applied by the actually used road roller; s4, when the sedimentation value of the particles does not change any more, the sedimentation value at the moment is the plastic stability value of the soil-rock mixed filler roadbed; and S5, when the average settlement value of the soil-rock mixed filler roadbed during construction reaches a plastic stability value, determining that the compaction quality of the soil-rock mixed roadbed meets the requirement. During actual construction, the plastic stability value serves as a judgment basis, if the average settlement value of the soil-rock mixed filler roadbed filler reaches or approaches the plastic stability value during construction, the compaction quality of the soil-rock mixed filler roadbed meets the requirement, the construction workload is reduced on the premise that the compaction quality is guaranteed, and the construction cost is reduced. And roadbed diseases in the later operation process are reduced.
本发明公开了一种土石混填路基施工压实质量控制方法，S1，建立土石混合填料路基的离散元模型；S2，在离散元模型中根据粒径生成不同等级的颗粒；S3，对离散元模型施加振动荷载，振动载荷大小与实际使用的压路机施加载荷相同；S4，当颗粒的沉降值不再变化时，此时的沉降值为土石混合填料路基的塑性安定值；S5，当施工时的土石混合填料路基沉降平均值达到塑性安定值时，则土石混合体路基压实质量满足要求。在实际施工时，将该塑性安定值作为判断依据，施工时的土石混合填料路基填料的沉降平均值达到或接近该塑性安定值，则土石混合体路基压实质量满足要求，在保证压实质量的前提下减小施工工作量，减小后期运营过程中路基病害的产生。
