沖擊碾壓加固吹填粉細砂地基機理及應用

Mechanism and application of impact compaction in foundation stabilization of hydraulic reclaimed silty fine sand ground

摘要: 從砂土液化的角度研究沖擊碾壓技術加固粉細砂地基的實質,揭示了沖擊碾壓技術加固此類粉細砂地基的作用機理.通過對首鋼曹妃甸吹填粉細砂地基處理中采用沖擊碾壓技術的工業實驗資料和效果進行分析研究,證明使用沖擊碾壓技術加固粉細砂地基是可行的.

Abstract: Based on the theory of sandy soil liquefaction,the working principle of impact compaction on silty fine sand ground was analyzed and the mechanics was put forward.An industrial trial was carried out on silty fine sand ground in Caofeidian District of Shougang Group,and the results and effects indicate that it is absolutely feasible to use this technology in this kind of situation.
