广岳线某滑坡工点变形及稳定性的动力分析

On dynamical analyses of a landslide workside deformation and stability along Guangyue railway

对于铁路线路工程,滑坡崩坍等地震次生地质灾害给线路的正常安全运营产生巨大的威胁。以广岳线某滑坡工点为例,运用FLAC-3D程序分别分析其在小震、中震及大震工况下的动力反应特性,较为真实地再现了滑波工点在汶川地震作用下的破坏特点。

To the railway engineering, the landslides and collapses along the railways wielded enormous influence on railway operation. A landslide along Guangyue railway was selected as an object in the paper, and FLAC-3D was used to analyze the seismic stability of the landslide under different seismic intensity of degree, reappeared the destruction feature of the slide under earthquake.
