【摘要】 对BEAM(Bore-Tunneling Electrical Ahead Monitoring)法实验土箱形状的设计进行了仿真研究,模拟了无限远边界和圆形、六边形、正方形等形状边界的电场分布情况,计算了各种土箱形状对应的电位分布与无限远边界电位分布的差异,最后确定圆形边界且中心位置偏移的土箱形状,可以最大限度地接近实际地电场的电位分布情况。更多还原

【Abstract】 A study on the soil box shape design by simulation for the BEAM method tunnel ahead exploration is carried out in this paper.The electric field distribution of the infinite boundary,round,hexagonal and square shape boundary has been simulated.The differences of the electric field distribution between the infinite boundary and various soil box shape boundary is calculated.We can finally confirm that the soil box with offset square boundary can maximize the conformity to the electric potential distribution of the real geoelectric field.更多还原
