洛湛铁路永州至岑溪段部分路段高填方软土地基需采用CFG桩加固处理,根据地质现状,对CFG桩的桩长、桩径、桩间距、桩体强度、褥垫层、加固范围进行设计。通过现场成桩试验,修订施工工艺,加强混凝土配合比、泵送灌注、捣固、抽样检测的控制,严格质量控制指标等措施,确保复合地基达标。 According to the geological status quo, the pile length, pile diameter, pile spacing, pile strength, cushion and reinforcement range of CFG pile should be carried out according to the geological conditions of the high fill soft foundation of some sections of Yongzhou-Cenxi section of Luoyang-Zhanjiang Railway design. Through the field pile test, revision of construction technology, strengthen the concrete mix, pumping, tamping, sampling and testing control, strict quality control indicators and other measures to ensure that the composite foundation compliance.
