| Abstract: | Here,taking a supporting engineering for deep foundation pit as the background,the three-dimensional finite difference model is established combining with FLAC3D software,and the construction process of the supporting structure with prestressed anchor-cable composite soil nails is simulated numerically and dynamically.The three dimensional distribution of the bracing structure displacements,the surrounding soil settlement,and the heave of the foundation pit bottom in the gradual process of excavation is res... |
