Simulation Evaluation of Electromagnetic Characteristics of Grouting Engineering Effect Based on Mineral Admixture

基于Maxwell software,以理论分析及仿真模拟为主要研究手段,结合现场测试,对水泥基灌浆材料在地层中的电磁特性进行模拟研究。通过建立各项同性地层模型,在中间设置灌浆材料,模拟灌浆材料因环境变化导致材料电磁特性发生变化的情况;通过改变电极距和灌浆材料性质,对不同极距、不同材料物性情况下空间电磁场的特性进行数值模拟,通过仿真模拟和现场测试,对不同供电极距情况下电磁响应特征进行分析,通过注浆前后电磁场特征的变化可对注浆的加固效果进行判断。

Based on Maxwell software,with the main research means of theoretical analysis and simulation,combined with field test,the electromagnetic characteristics of cement-based grouting materials in the stratum are simulated.Through isotropic stratum model,grouting materials are set in the middle to simulate the changes of electromagnetic characteristics of grouting materials due to environmental changes.By changing electrode distance and grouting material properties,numerical model of space electromagnetic field characteristics under different electrode distances and material properties is carried out,and the verification test is carried out.Through simulation study and field test,the electromagnetic response characteristics of different pole distances are analyzed.It is proved that the reinforcement effect can be judged by analyzing change of electromagnetic field characteristics before and after grouting.
