项目摘要

1.Recycle of empty tins as Light-Fill Materials(1) The plastic unit within the empty tins was developed and the light-fill made by the plastic unit was constructed and traffic load was operated. As the results of traffic experiments, the light-fill made by the plastic unit within the 9 empty tins was clarified to be able to sustain D type traffic (12t wheel load).(2) As the results of the proof erosion tests of empty tins exposed under the natural weather during 1 month to 9 years, It has been judged that the plastic units without any proof erosion can be used as the temporary light-fill load embankment within 5 years.2. Recycle of coal ash, volcanic ash and EPS wastes as a constructing materials(1) New tile mixed by coal ash, volcanic ash and clay was developed.(2) New constructing material(hereafter, called EPS wastes ash)mixed by coal ash, EPS wastes, Portland cement and water was developed.Laboratory investigation was carried out unconfined compression tests and penetration tests a … More s like as CBR tests on the EPS wastes ash specimen with various conditions of mix proportion, and curing time.From the results of laboratory testing of EPS waste ash, the mix proportion of compertibility (the mass ratio of cement to Fly ash (FA) , C/F>17%, the mass ratio of EPS wastes to FA<0.5%) and curing time (28 days) for the thin layr improvement material for soft clay ground were determined.(3) The 1g small scale footing model tests for the soft clay ground improved thin layr with the EPS wastes ash regulated C/F=20% and EPS/F=0.5% was carried out. As the results of the footing model test, the bearing capacity, q_d of the improved soft ground is increasing with increase of the depth, D_f and width, B of thin layr of the EPS waste ash. The increase of bearing capacity to compare with unreinforced ground is 2.4 times at Df/D=0.044, and 3.0 times at Df/D=0.11 under the condition of the clay ground depth, D=50cm, the footing width, b=10cm and B=20cm.(4) The model parameters of the elasto-visco/plastic FEM were determined with the comparison of both model tests and calculated results for the design guide of the soft clay ground improved thin layr with the EPS wastes by in-situ scale simulations.

1.空罐回收作为轻质填充材料（1）开发空罐内的塑料单元，并构建由塑料单元制成的轻质填充并运行交通负载。交通试验结果表明，9个空罐内的塑料单元轻填能够承受D型交通（12t轮重）。（2）空罐在自然气候下暴露1个月至9年的耐侵蚀试验结果，判断没有任何耐侵蚀的塑料单元可以作为5年内的临时轻填荷载路堤。2．粉煤灰、火山灰、EPS废弃物回收作为建筑材料（1）开发了粉煤灰、火山灰、粘土混合的新型瓦。（2）开发了粉煤灰、EPS废弃物、硅酸盐水泥和水混合的新型建筑材料（以下简称EPS废灰）。实验室研究进行了无侧限压缩试验和渗透试验，类似于CBR试验 EPS废灰试件具有多种配合比和养护时间条件。根据EPS废灰的实验室测试结果，确定了软粘土地基薄层改良材料的相容性配合比（水泥与粉煤灰（FA）的质量比（FA），C/F>17%，EPS废灰与FA的质量比<0.5%）和养护时间（28天）。（3）1g小规模对EPS废灰调节C/F=20%、EPS/F=0.5%的软粘土地基改良薄层进行基础模型试验。基础模型试验结果表明，改良软土地基的承载力q_d随着EPS废灰薄层深度D_f和宽度B的增加而增加。在粘土地层深度D=50cm、基脚宽度b=10cm、B=20cm条件下，与无筋地基相比，Df/D=0.044时承载力提高了2.4倍，Df/D=0.11时承载力提高了3.0倍。(4)通过对比两种模型试验和计算结果，确定了弹粘/塑性有限元模型参数，为设计指导提供依据。通过原位尺度模拟，用 EPS 废物改善了软粘土地基的薄层。较少的
