聚苯乙烯轻质混合土抗压强度特性试验研究

Study on compressive strength properties of light heterogeneous soil mixed with expanded polystyrene

通过室内试验,研究聚苯乙烯轻质混合土轻质、高强的相关关系,揭示出轻质混合土抗压强度与水泥掺入比、含水量、密度、龄期和破坏应变的关系,以及不同水泥掺入比和密度时的应力-应变关系,给出了强度预测公式和应力-应变拟合关系,为工程应用提供科学依据。

Based on laboratory experiments, the correlativity between light weight and high strength of the light heterogeneous soil mixed with polystyrene is studied. The authors demonstrate the relations between compressive strength and cement content, moisture content, density, age and failure strain. The compressive stress-strain behavior with different cement contents and densities is also analyzed. Finally, the authors suggest a strength formula and a relationship of stress-strain, which can be used as the scientific basis in-engineering applications.
