摘要:
 以大冶黏土为研究对象，将EPS颗粒掺入水泥黏土中分别进行静三轴与动三轴试验，研究在不同围压与EPS颗粒粒径的条件下，改良土体的静、动弹性模量变化规律。试验结果表明：在围压相同、EPS颗粒粒径不同条件下，随着EPS颗粒粒径的增大，其静、动弹性模量逐渐减小；在EPS颗粒粒径相同、围压不同条件下，随着围压的增大，其静、动弹性模量逐渐增大；在围压和EPS颗粒粒径都相同的条件下，静弹性模量与动弹性模量变化趋势均一致。该试验结果可为相关工程提供参考依据。
Abstract:
 Taking Daye clay as the research object, the static triaxial and dynamic triaxial tests were carried out by mixing EPS particles into cement clay, respectively, to study the changes of static and dynamic elastic modulus of improved soil under different confining pressures and EPS particle sizes. The experimental results show that under the same confining pressure and different particle sizes of EPS, the static and dynamic elastic moduli of EPS decrease gradually with the increase of particle sizes of EPS. Under the conditions of the same particle size and different confining pressures, the static and dynamic elastic moduli of EPS increase gradually with the increase of confining pressures. Under the condition of the same confining pressure and EPS particle size, the static elastic modulus and dynamic elastic modulus change trend are consistent. The test results can provide reference for related projects.
