中文摘要弹性模量是固化土一项基本的力学性能指标,直接影响结构的静力和动力力学分析计算,对弹性模量的试验研究具有重要的实际意义。针对固化土弹性模量研究薄弱的问题,以自主研发的MBER土壤固化剂为研究对象,通过对杨凌试验区土样进行室内试验,分别对影响MBER固化土的弹性模量的土壤固化剂剂量、不同含水率和不同龄期3种因素进行分析研究。根据试验结果,获得了MBER固化土应力—应变关系曲线,得出固化土弹性模量在300~1 000MPa。固化土的弹性模量随着土壤固化剂剂量,含水率及龄期的增长呈增加趋势,而当含水率达到一定值时,固化土的弹性模量呈下降趋势。因此,通过合理控制土壤固化剂剂量及含水率,能够改善固化土的力学性能,进而达到改良固化土的目的。
英文摘要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 300and 1 000MPa.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.
