摘要

中文摘要: 在普通高水材料中掺入一定比例的固体骨料，不但可以降高水材料的成本，而且可以改善高水材料充填体的物理力学性质。在对普通高水材料基本性质测试分析的基础上，对掺杂后的新型改性高水材料进行了试验研究。采用土力学中的三轴试验方法，设置了掺杂骨料粒径分别为5~10mm、10~20mm、20~40mm、40~60mm、无掺杂试件、混合骨料试件和河沙试件的实验组，对以不同粒径作为掺杂骨料的圆柱试件进行了固结不排水剪切实验。测试结果表明：不同掺杂粒径对试件的强度和物理力学参数有重大影响；同样掺入比例条件下，掺入的固体粒径越小，掺杂改性后的高水材料强度越高；混合试件和河沙试件的强度和力学参数要明显优于掺杂单一粒径的试件。证明了使用碎石骨料作为掺杂改性材料，不但可以降低高水材料的成本，而且可以改善高水材料充填体的物理力学特征。

Abstract

Abstract: Mixed with a certain proportion of solid aggregate

not only the costs of high-water-concretion can be reduced

but the physical and mechanical properties of the high-water-concretion can be improve. Based on the basic property of the high-water-concretion

the new modified high-water-concretion after doping was studied. By using soil mechanics’ triaxial testing methods

the specimens which were separately incorporated in the aggregate size were 5~10mm

10~20mm

20~40mm

40~60mm

non-doped

the mixed and the river sand’ s aggregate were performed of consolidated undraining shear test. The results showed that different doping particle have a significant impact on the strength and mechanical parameters of the specimen：The smaller the particle size

the higher the strength and the mechanical parameters; the strength and mechanical parameters of mixing specimen and river sand specimen is much better than a single particle doping specimen. These experiments prove that the use of gravel aggregate doped material to the material for high-water-concretion has a strong feasibility.
