The fluid solidified soil can be used in the narrow space because of its good fluidity,and the external fiber can effectively improve its mechanical properties and water stability.In order to understand the curing effect of fiber reinforced fluidized solidified soil,0.1％～0.5％glass fiber was mixed into the fluidized solidified soil,and compressive and flexural strength tests,water stability tests and SEM microscopic tests were carried out on the fiber-doped specimens.The results show that with the increase of glass fiber content,the fluidity of fluidized solidified soil decreases gradually.When the glass fiber content was 0.4％,the compressive strength and flexural strength of 28 d reached the peak,which were in-creased by 13.4％and 58.1％respectively compared with the specimens without fiber at the same age.When the glass fi-ber content was 0.3％,the 28-day water stability coefficient reached the peak,which was 23.1％higher than that of the unmixed fiber specimens of the same age.The staggered overlapping of fibers forms a fiber network structure and the an-choring force of fibers on soil is the mechanism of action of fiber-enhanced soil mechanical properties.
