Damage evolution laws are analyzed by the load - unload tests . analysis results show that obvious damage occurs in the inner of the cemented soil stabilized with nanometer silica fume and the added nanometer silica fume can improve the damage 研究表明，纳米硅粉水泥土内部存在明显的损伤现象，掺加纳米硅粉，水泥土损伤特性发生改变：与试验曲线的对比结果表明，本文采用的损伤变量和损伤模型能够较真实地反映纳米硅粉水泥土的损伤特性。
