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 摘要針對常張高速公路采用沖擊壓實技術壓實土石混填路基的問題,選取試驗段進行了不同虛鋪厚度路基的施工工藝及質量控制等試驗研究,提出了虛鋪厚度、沖壓遍數、沖壓沉降率(單級沉降量) 、填料最大粒徑等施工控制參數。

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 其中不同虛鋪厚度填料有相應的最佳碾壓遙數,并從技術經濟的角度提出了最佳的虛鋪厚度及其碾壓遍數,并建議施工控制以沉降率為主。
