The glacial gravel has high strength but couldn t be compacted easily;the filling materials made of glacial gravels in Jiangpinghe CFRD are compacted by impulsive vibro-roller,the compacted lift reaches 120 cm and the compactness is greatly improved;so the consturction progress of the dam is quickened and the cost is cut down.
冰渍砾岩填筑高面板堆石坝在国内外尚没有先例,其岩石强度高,不易碾压密实,采用冲击式振动碾碾压后,填料的压实密度得到了明显提高,铺料厚度也可以达到120 cm,对提高施工质量、加快施工进度和节约工程投资都具有显著的效果。
According to the design requirement and geographical condition of Shanghai Waigaoqiao Port Area, and in the light of different thickness of reclaimed silty sand and different substrata, various foundation improvement measures including vibro-rolling combining with dynamic dewatering, low-energy dynamic tamping combining with dynamic dewatering, and non-filler vibro-flotation, etc.
根据上海外高桥港区建设的设计要求和地质条件,对不同的吹填粉细砂厚度及不同的下卧层地基,分别采用振动碾压联合动力降水加固技术,低能量强夯联合动力降水加固技术,无填料振冲加固技术进行地基处理。
1 testing Area in 1 stage Project of Yangshan Deepwater Harbor Area it is proved that to adopt the construction process of reasonable vibro-jet with vibration rolling so as to effectively improve the capacity of the base and reach the use requirement of the roads and stack yard in the container harbor area, at the same time, with easy and r.
通过洋山深水港区一期工程1#试验区的加固试验证明,采取合理的振冲辅以振动碾压的施工工艺,有效地提高了地基承载力,达到集装箱港区道路、堆场的使用要求,且施工方便、快速。
To design an effectually mixture, the interaction between mixture and vibration rolling must be considered.
R法的基础上 ,施加动荷载的简化试验方法 ,分析级配碎石混合料的动力变形特性 ,可用永久变形、弹性模量双指标指导混合料的组成设计 ,而合理的级配碎石基层材料组成 ,应考虑到材料与振动碾压工艺的相互作用。
