振冲碎石桩在平潭长江澳风电场的应用

根据平潭长江澳风电场工程特点,对岩土参数进行分析,评价其工程性能。为了地基基础的安全可靠、经济合理,本工程建议用振冲碎石桩作为地基处理措施,并进行计算分析,提出设计方案。通过对复合地基原体试验检测成果的分析,论证了在沿海液化砂土中采用振冲碎石桩加固地基,对于消除砂土液化、提高地基承载力、减少变形是可行的。

The Application of Vibro Replacement Stone Column at Pingtan Changjiangao Wind Power Station

According to the project characteristic at Pingtan Changjiang AoWind Power Station,this paper analyzes its soil parameter,and evaluates its engineering behaviors.For the foundation's safety and economy,vibro replacement stone column as a treating foundation countermeasure is suggested to the construction site.By theoretical analysis and calculation,a design scheme is recommended.With analyzing the result of the prototype testing in the composite foundation,it is proved that vibro replacement stone column is applied to treat the foundation of sand liquefaction in the coast.To eliminate sand liquefaction,increase soil bearing capacity,and reduce foundation settlement,vibro replacement stone column is satisfying.
