MBER固化土弹性模量的试验研究
Experimental Research on Elastic Modulus of MBER Solidified Soil
摘要
Abstract
As one of the indices for basic mechanical properties of stabilized soil,elasticity modulus affects structure′s static and dynamic analysis and calculation.So,experimental research on elasticity modulus is of practical significance.In view of few researches on elasticity modulus of stabilized soil and by taking the independently developed soil stabilizer as a research object,the three factors of soil stabilizer dosages,different moisture contents and different ages affecting the MBER stabilized-soil′s elasticity modulus are separately studied by laboratory experiment using soil samples collected in Yangling experimental area.A stress-strain relationship curve is obtained from experimental result and the stabilized-soil′s elasticity modulus is found to be between 300 and 1 000 MPa.The stabilized-soil′s elasticity modulus is increased with the increases in soil stabilizer dosage,moisture content and age and however,it begins to drop down as a threshold value of moisture content occurs.By reasonably controlling soil stabilizer dosage and moisture content,mechanical properties of the stabilized soil can be improved for an improved stabilized soil.关键词
