摘要:In order to better use the cast-in-situ foamed lightweight soil for soft soil roadbed filling project, based on mechanical properties test under different working conditions study unconfined compressive strength variation characteristics of cast-in-place foamed lightweight soil. Analysis of tension and bending strength and fatigue life of the cast-in-situ foamed lightweight soil by fatigue resistance test. The corrosion resistance test was used to further analyze the unconfined compressive strength loss and mass loss of the cast-in-situ foamed lightweight soil under different corrosion conditions. The results show that as soft foundation backfill material its mechanical properties are excellent, however, the fatigue life is greatly affected by the stress ratio, and the cast-in-situ foamed lightweight soil is poor in acid corrosion resistance, diesel corrosion resistance and salt-spray corrosion resistance.
