地面超载对土钉墙工作性能影响的有限元分析
Finite Element Analysis of Influence of the Ground Overload on Working Performance of Soil Nailed Wall
摘要
Abstract
In order to reveal the rules of the stress and deformation of the soil nailed wall under the action of ground overload , the construction process of excavation and supporting of the soil nailed wall for deep foundation exca -vation was simulated through establishing a whole three-dimensional finite element model on the basis of the finite ele-ment method .The influence of the horizontal displacement of excavation face , the subsidence displacement of the ground beside the foundation pit , the bottom heave displacement and the axial forces of soil nails on different ground o -verload were analysized .The results showed that with the increase of the ground overload ,the horizontal displacement of excavation face , the subsidence displacement of the ground beside the foundation pit were increased approximately linearly, the ground overload had little effect on the bottom heave displacement , the effect of ground overload on the upper the axial forces of soil nails was larger than that of the lower .关键词
