The variety of pore water pressure with time during earthquake and the distribution of pore water pressure after earthquake were investigated in the dynamic analysis , and the acceleration action process of partial nodes and the shear stress variety process of partial elements were also obtained 动力分析中详细给出了坝体在地震期间孔压变化过程及震后的孔压分布,并给出了部分结点的加速度反应时程及部分单元的剪应力时程。
Through strength tests and xrd tests for cemented stone , the paper presents action mechanism of the nanometer materials in the cement hydration and hardening process : pozzolanic effect , filling effect , acceleration action for the cement hydration , and improving action for microstructure . from the four aspects , the modified mechanism of the nanometer silica fume and ordinary silica fume in cement paste are compared . the analysis results show that the particular properties of the nanometer silica fume include particle fineness , crystal structure and surface hydroxy , etc . a serial of laboratory tests are performed to study physical and mechanic properties of the clay with the addition of the nanometer silica fume 结合水泥石强度试验和xrd试验,从火山灰效应、填充效应、水泥水化促进作用和微结构改善作用等方面探讨了三种纳米矿粉在水泥水化硬化过程中的作用机理;从这四个方面出发,对比分析了纳米硅粉和普通硅粉作用机理的异同点,分析表明,纳米硅粉的优异特性主要表现为颗粒细度、晶体结构、表面羟基等特性。
