路堑边坡浅层塌滑的控制因素与生态防治措施OACSTPCD
Analysis on factors controlling shallow failures of the cut slopes and its prevention by bio-engineering measures:A case study of the cut slopes along the highway from Shuangcheng to Dajiali
有效掌握边坡浅层塌滑机制及其影响因素的主次关系是开展路堑边坡变形预测及塌滑治理的重要前提.为此,以阵雨条件下甘肃省双达高速某路堑边坡为研究对象,首先通过FLAC3D有限元软件平台编写FISH语言,实现饱和度、重度和土体抗剪强度之间的动态关联,然后求解不同降雨强度、坡比和降雨历时条件下路堑边坡的安全系数,并基于灰色关联理论确定路堑边坡浅层塌滑主要外界因素的主次关系,最后通过室内降雨试验和现场生态防护试验总结出路堑边坡浅层塌滑机制,提出浅层塌滑生态防…查看全部>>
Understanding the primary and secondary relations of influencing factors is crucial for predicting deformation and controlling collapse in cutting slopes.Using a cutting slope along the Shuangcheng to Dalijia expressway in Gansu Province as the research object,this research utilized the FLAC3D finite element software platform to establish dynamic correlations between saturation,gravity,and soil shear strength through FISH language.Based on this,safety factor…查看全部>>
