【摘要】 运用弹塑性有限元法及极限平衡理论,定量分析了软弱夹层性状,如软弱夹层在地基中的相对位置,厚度的不均匀性等对斜坡软弱地基填方工程稳定性的影响。研究结果表明,软弱夹层位于地基表面时,更易发生失稳现象,下坡脚软弱夹层厚度比上坡脚显著增大时将加剧失稳趋势,必须采取有针对性的工程措施,并对工程措施的具体实施提出了自己的意见。更多还原

【Abstract】 FEM and limit equilibrium theory were conducted to analyze the impact of weak layer behavior to thestability of subgrade embankment on sloped weak ground, such as the relative position in the foundation and theuniform of thickness. Research results show that it has more tendency to lose stability when the weak layer islocated in the foundation surface and rigorous guide in the design and construction phases in infrastructuredevelopment was presented.更多还原
