| 摘 要： | 基于不同水压下混凝土的内部孔隙水压力试验数据,采用ANSYS有限元分析软件,进行了围压水作用下混凝土孔隙水压力变化瞬态反演模拟,并与试验结果进行对比分析。结果表明:混凝土内部孔隙水压力的变化过程与试验所得变化过程基本一致。说明所建瞬态分析反演数学模型能够用来对围压水作用下混凝土的渗透系数进行反演计算,并且所得到的结果能够与试验结果较好的吻合,具有一定的可靠性。

| Abstract: | Based on the internal pore water pressure test data of concrete under different water pressures,the ANSYS finite element analysis software is used to simulate the transient inversion of concrete pore water pressure under confining water,and the inversion results are compared with experimental results.It is found that the obtained results can be well matched with the experimental results,which show that the constructed transient analysis inversion mathematical model can be used to inversely calculate the permeability coefficient of concrete under confining water and have certain reliability. |
