摘　　要：橡胶混凝土由于在某些性能上的优势,具有广阔的发展空间和应用前景。影响其性能的主要因素有:水灰比、橡胶细度和橡胶掺量。采用正交试验方法,以抗压和抗折强度为性能指标,通过回归分析和极差方差分析确定抗压和抗折强度影响因素的显著性大小,得出了水灰比影响最大,橡胶细度和掺量有一定影响。其为工程实践提供一定的参考。Because of some performance advantages, rubber concrete has a broad space for development and applicationprospect. The main factors affecting its performance are water cement ratio, rubber fineness and rubber dosage. This paperadoptsorthogonal experiment, takes the compressive strength and flexural strength as performance indexes, determines thesignificance of the main factors affecting the compressive strength and flexural strength by regression analysis and varianceanalysis, and a conclusion is obtained ： the influence of water-cement ratio is significant, the rubber fineness and rubber dos-age have little influence. The paper＇s results can provide a certain reference for the engineering practice.
