| 摘 要： | 土工加筋结构在工程实际中被广泛采用,采用基于极限分析理论上限法对其稳定性能的分析比较常见.但目前基于极限分析法的加筋边坡稳定性常常采用的评定指标(临界高度Hcr、稳定性系数Ns或临界加筋强度Ko)与其他常用方法(极限平衡法、数值分析法)采用的安全系数(Fs)评定指标不完全统一,故该分析方式往往无法在实际工程中直接应用....

| Abstract: | The reinforced soil structures are employed widely due to the technical and economical advantages in static state.The selected evaluation index(critical height Hcr,critical reinforcement strength k0 or stability coefficient Ns) based on the limit analysis theorem for reinforcement slope stability,which is different from the evaluation index(safety factor Fs) based on other common methods such as the limit equilibrium method and the numerical analysis method,is inconvenient for application during the enginee... |
