干湿循环下石灰黄土垫层透水性和强度变化试验
Test study on the permeability and strength variation of lime loess bedding under wetting and drying cycles
摘要
Abstract
Based on the design parameters of lime soil bedding under permeable concrete in imperial road engineering, in Xi' an Da Ming Gong national archaeological site park, the uniaxial compressive test, variable head permeability test and fast direct shearing test of lime loess on age 35 d were accomplished under ten wetting and drying cycles. Test results shows that, the fast direct shearing strength and permeability coefficient both decrease exponentially with the number of wetting and drying cycles if without consideration of moisture content, and the fitting curve and equation is according with the measured values well. Furthermore, the influence of wetting and drying cycles on the uniaxial compressive strength on age 35d is not obvious if without consideration of the moisture content of lime loess, with small variation of uniaxial compressive strength, which justify that the uniaxial compressive strength on age 35d of lime loess treated with lime of dry mass ratio 15％ is stable under wetting and drying cycles,and the moisture content of lime soil is influent to the variation rule of the uniaxial compressive strength with the wetting and drying cycles.关键词
