This paper uses the software named Volview3.4 which is useful for reconstruction and image analysis of 3D macropores space networks of soil samples from CT data. The results show that the Volview3.4 software is useful for 3D reconstruction from 2D CT image series;The CT scanning interlayer distance has a great influence on the display effect of CT images after 3D reconstruction. Theoretically, the smaller the CT scanning interlayer distance is, the better display effect of 3D reconstruction is from CT images.%本文利用Volview3.4软件并依据VR法对CT扫描土样进行三维重构，并实现了土体大孔隙的三维可视化。结果表明：运用三维可视化软件Volview3.4对二维CT序列图像进行三维重构，其效果较理想；从图像显示方面来看，CT扫描的层间距对三维重构后的图像的质量有很大的影响，理论上扫描层间距越小其三维重建后显示的效果越好。
