摘要

通过材料性能试验、土工离心模型试验和数值计算，研究陶粒粉煤灰混凝土的物理力学性能及其在桥涵台背回填的应用效果。首先，通过材料性能试验研究不同配合比的陶粒粉煤灰混凝土的物理力学性能；其次，通过土工离心模型试验和数值计算研究陶粒粉煤灰混凝土用作桥涵台背回填材料时，作用于台背的土压力和回填体的变形特性。研究发现：陶粒粉煤灰混凝土具有轻质、高强度、高模量和易施工等诸多优点；陶粒粉煤灰混凝土回填体作用于台背的土压力明显小于常规回填材料；回填区和地基的沉降变形亦明显小于其他材料。结果表明：陶粒粉煤灰混凝土作为台背回填材料具有明显的优越性，是一种值得推荐的桥涵台背回填材料。

Abstract

The mechanical properties of argil fly-ash concrete and effectiveness of its application to abutment-backfill are investigated by material experiment

centrifugal modeling test and numerical calculation. It is pointed that the properties of argil fly-ash concrete are superior to that of other backfill materials. Its properties have the advantages of light mass

high strength and high modulus. In addition

its construction method is different to that of other materials. Its soil pressure and settlement are smaller than that of other materials markedly. Consequently

the results indicate that the argil fly-ash concrete is recommendable backfill material.
