较深海域振冲碎石桩地基处理试验研究

The test research on gravel pile foundation treatment in deeper sea

结合大连某工程实例,介绍了较深海域振冲碎石桩地基处理过程及设计参数,总结了海上振冲碎石桩施工过程中的注意事项,并对该项目试验区地基处理效果进行了评价,指出振冲碎石桩地基处理方法在水深20 m左右的海域条件下可行,结果满足常规应用所需承载力要求。

Combining with an engineering example in Dalian,this paper introduced the foundation treatment process and design parameters of deeper sea gravel pile,summarized the attentions in sea gravel pile construction process,and evaluated the foundation treatment effect of the project test area,pointed out that the gravel pile foundation treatment method was feasible at a depth of about 20 m sea condition,the results met the required capacity requirements of routine application.
