The test shows that optimum shocking and compaction quantities is different to different virtual height of packing materials , and optimum virtual height and shocking and compaction quantities is put forward 其中不同虚铺厚度填料有相应的最佳碾压遥数，并从技术经济的角度提出了最佳的虚铺厚度及其碾压遍数，并建议施工控制以沉降率为主。

The soil - rock foundation was applied in highway of changde - zhangjiajie , and in order to assure soil - rock foundation quality by shocking and compaction test , different virtual height of soil - rock foundation was constructed and it ' s quality was controlled for in - situ test , it was considered as parameter for virtual height , shocking and compaction quantities , shocking and compaction sediment rate and maximum diameter of packing materials 摘要针对常张高速公路采用冲击压实技术压实土石混填路基的问题，选取试验段进行了不同虚铺厚度路基的施工工艺及质量控制等试验研究，提出了虚铺厚度、冲压遍数、冲压沉降率（单级沉降量） 、填料最大粒径等施工控制参数。
