摘要
根据佛开高速公路改扩建工程建设特点,对佛开高速公路拓宽加筋陡路堤设计方案进行离心模型试验,确定该设计的安全可靠度。通过不加筋和加筋拓宽路堤模型试验,对比分析加筋对拓宽路堤位移的影响,获得加筋路堤稳定性的增强幅度。改变加筋层的间距,寻找加筋间距对路堤变形的影响规律,确定合理的加筋层间距。
Embankment widening technology by reinforcement slope without more land is presented considering the characteristics of Fo-Kai Expressway.Centrifuge model tests are carried out for verification of the design scheme of Fo-Kai Expressway extension project.The results show that the widening embankment reinforcement technology without more land is safe and reliable.A comparison of deformation characteristics between unreinforced and reinforced models for the widening embankment is made,the effect of geogrid spacing on deformation of the widening embankment is studied.
