摘要
泡沫塑料颗粒轻质混合土是一种新型的轻质土工材料。它具有轻质、高强、自立性好、施工工期短及废物再生利用和环境保护的优点,因此在工程中具有极广泛的应用前景。对不同 EPS 颗粒添加量的泡沫塑料颗粒轻质混合土试样,进行了固结不排水三轴剪切试验。试验结果表明:EPS 颗粒添加量对轴向应变-孔压曲线(ε_a-u)及孔压系数 A_f 都有较大的影响。
The EPS beads treated lightweight soil, a new type of light weight geo-material, has promising future because of advantages such as light weight, high strength, self-standing, shorter project execution time, re-utilization of surplus soils, protection the environment against pollution. The pore water pressure properties of different additive rates of EPS beads specimen have been researched by consolidated-undrained triaxial test. Test results show that the additive rates of EPS beads has heavy effect on the curve of εa - u and pore pressure coefficient Af.
