基于ABAQUS的边坡降雨稳定性分析可靠性研究
|
摘要
文章以台州马头山边坡为研究对象,通过在滑坡体现场设置降雨量、应力、位移观测设备,记录强降雨条件下滑坡体各项参数的变化规律,并结合现场勘查滑坡体地形、地质资料,采用ABAQU有限元分析软件对边坡稳定性进行模拟分析,以验证基于ABAQUS的有限元分析方法在边坡降雨稳定性分析中的可靠程度。通过对比发现模拟分析所得数据与现场实际观测数据较为接近,误差约在7%左右,可为后续推广基于ABAQUS的模拟分析方法及为设计、施工及运营过程中的边坡预警等研究提供参考。
With Taizhou Matoushan slope as the research object,by setting the rainfall,stress,and dis-placement observation equipment at the landslide field,this article recorded the variation rules of all parameters of landslide objects under the conditions of heavy rainfall,and in combination with the site survey of landslide topographic and geological data,it conducted the simulation analysis of slope sta-bility by using the finite element analysis software ABAQU,in order to verify the reliability of ABAQUS finite element analysis method in the slope rainfall stability analysis. By comparison,it was found that the data obtained from simulation analysis is closer to the actual observation data,and the error is about 7%,which can provide a reference for subsequent promotion of ABAQUS-based simulation analysis method as well as for the early slope warning during design,construction and operation.
