摘要
阐述在区域性大型断层带的软基处理中运用"水上浮桥"的建模思维方式,根据路基岩土体孔隙率大、松散的特点,采用固结灌浆从挖掘岩土体本身的潜力提高地基承载力,固结灌浆岩土体使准连续配筋混凝土地下筏板基础与摩擦型钢管微桩有机结合,以此提高运煤特重交通路基的整体强度。
During treatment of soft soft subgrade located in large regional fault zone, model of floating bridge above water is adopted. Based on characteristics of subgrade soil with large porosity and loose, consolidation grouting method is used to raise load capacity of subgrade which can confine underground reinforced concrete raft foundation with steel pipe friction micro-pile to improve integrity strength of special heavy traffic soil subgrade.
