摘要
基于刚性桩破坏以弯曲破坏控制,通过力学推导,建立了刚性桩处理软土路基稳定计算的简化分析方法。简化方法将刚性桩弯曲破坏时对边坡稳定性的贡献转化为等效土体的抗剪强度的增加,通过多次迭代计算,获得边坡最终的边坡安全系数。文中采用上述简化分析方法,以福州连江粗芦岛某二级公路软基处理工程为例,介绍了简化分析方法在实践中的应用,研究成果对类似工程的路基的设计和施工具有重要的参考意义。
Based on the failure of rigid pile composite foundationands is controled by bending failure of the piles,a simplified analysis method for the stability analysis of rigid pile composite foundations was established.The simplified method converts the contribution of the rigid pile to the slope stability into an increasing in the shear strength of the equivalent soil.Through multiple iterative calculations,the final slope safety factor of the slope is obtained.Using the above-mentioned simplified analysis method,a project of a secondary road in Fuzhou Lianjiang Culu island was introduced as an example.The research results have important reference significance for the designation and construction of roadbeds of similar projects.
