橡胶颗粒混合砂抗液化性能研究

摘要:

为了探究橡胶颗粒掺入砂土路基制成混合砂材料时的抗液化性能，本文通过筛分试验及动三轴试验开展相关研究，分别分析了橡胶颗粒掺量、粒径及混合砂材料的围压大小、固结比等变化对混合砂试样动孔隙水压力的影响规律，从而评价其对抗液化性能的影响。结果表明：橡胶颗粒掺量、粒径、围压及固结比均是影响混合砂材料抗液化性能的主要因素，且呈正相关变化趋势。

Abstract:

In order to explore the anti-liquefaction performance of mixed sand materials when rubber particles are mixed into sandy soil roadbeds, this paper carries out related research through screening tests and dynamic triaxial tests. The influence of changes in pressure, consolidation ratio, etc. on the dynamic pore water pressure of the mixed sand sample, so as to evaluate the impact of its anti-liquefaction performance. The results show that the content of rubber particles, particle size, confining pressure and consolidation ratio are the main factors affecting the anti-liquefaction performance of mixed sand materials, and they show a positive correlation trend.
