摘要
基于滑坡作用下的地质灾害,使用ADINA有限元软件建立三维有限元模型,设置接触单元来模拟管—土之间的相互作用,对滑坡作用下的大直径埋地管道的力学性能进行分析,分别计算了不同影响参数情况下滑坡土体作用对埋地管道的力学影响,并对各种参数下的应力、应变以及位移云图等进行分析,得到了一些影响参数的规律性结论。
Based on the geological disasters under the effect of the landslides,the paper adopts ADINA,the finite element software,to establish the three-dimension finite element model,simulates the interactive effect between the pile and soil by allocating the contact elements,analyzes the dynamic performance of the large-diameter buried pipelines under the effect of landslides,calculates the dynamic influence of the landslides soil on the buried pipelines under various influential parameter,analyzes the stresses,strains and the displacement cloud pictures,and achieves some conclusion on the rule for some of these parameter.
