地面塌陷对城市地埋管线影响的试验研究及数值分析
Experimental Study and Numerical Analysis on Influence of Urban Underground Pipelines under the Ground Collapse
摘要
Abstract
In this paper ,based on the experimental results of Geotechnical Slot ,the deforma_tion and internal forces of the buried pipeline during ground collapse have been analysed .During the Geotechnical Slot experiment ,the subgrade soil under the pipeline was excavated to simulate the soil collapse .Furthermore ,with the three_dimensional finite element model the nonlinear anal_ysis was performed to probe the bearing behavior of the undergroud pileline ,and the soil model was executed by Gradual Killed Method in ANSYS software during the FEM calculation .The cal_culation results are in good agreement with the experimental data about pipeline displacement and strain .The research method can provide a new analytical approach for the prediction and preven_tion of the consequences of the ground collapse .关键词
