摘要:
泉州市安吉路软基段的中间主车道路基采用排水固结法处理,两侧非机动车道下的管沟地基采用粉喷桩复合地基处理 .通过对试验路段的地基总沉降、分层沉降、孔隙水压力等实测资料的分析,比较堆载预压法和真空堆载联合预压法,及其在有侧限条件下的处理效果 .分析结果表明,在有侧限情况下,真空堆载联合预压法比堆载预压法的加固效果要好,但对工期不紧、非超软地基或存在强透水层地基的城市道路软基,是否采用真空堆载联合预压法尚应进行技术经济比较
Abstract:
Anji road in Quanzhou is an arterial road of city. The foundation of main traffic lane in the centre of its soft foundation section is treated by adopting the method of drainage and consolidation, while the pipe duct foundation under bilateral bicycle lanes is treated by adopting DJM pile composite foundation, Through analysis of such measured data as general setting of subgrade, setting of subgrade in layers, and pore water pressure, the author compares the precompressed effect of loading and that of vacuum loading under lateral restraining condition. With lateral restraint, vacuum loading as a precompressed method shows a better consolidation effect than that of loading.However, whether or not vacuum loading precompression is suitable for the soft foundation of city road where construction period is not urgent, the foundation is not excessive soft, or there exists a layer of serious water permeability in the foundation, it needs a comparison in technical economy.
