泡沫塑料颗粒种类对轻质混合土力学特性的影响

Effects of the Type of Expanded Poly-styrene Beads on the Mechanical Properties of Lightweight Treated Soil

摘要:

轻质混合土是一种新型的轻质土工材料,具有轻质、环保、高强等特点。本文对添加不同种类泡沫塑料颗粒的轻质混合土试样进行了无侧限抗压强度试验、等向压缩试验及三轴剪切试验。试验结果表明:泡沫塑料颗粒种类对轻质混合试样的力学特性有较大的影响。

Abstract:

The lightweight treated soil （ LWTS ）, a new type of light weight geo-material （ LGM）, has advantages such as light weight, high strength and environment protection et al.. The mechanics properties of two type of the LWTS mixed with different foamed plastic beads are researched by the uniaxial compression test, the isotropic compression test and the triaxial compression test. The results show that the type of beads has greater effect on the mechanics properties of LWTS.
