基于抛物索理论的加筋土调整不均匀沉降研究
Study of reinforced soil adjusted to differential settlement based on parabolic cable theory
摘要
Abstract
Heterogeneous settlement is a common engineering problem in the soft soil foundation or at the juncture between new and old subgrade induced by consolidation settlement,rainfall or earthquake.The reinforced soil structure is commonly applied to reduce the unequal settlement in practices.However,less attention goes to theoretical research on the deformation of reinforcing material under differential settlement condition at present.To improve and simplify the design theory of reinforced earth structure,the deformation of reinforcement in reinforced soil structure is investigated based on the theory of parabolic cable.A method is developed to calculate reinforcement material deformation under differential settlement condition.The feasibility and accuracy of the proposed method are verified by laboratory experiment and theoretical analysis.The method does not require repeated numerical simulation.The calculation results can satisfy the needs of the actual project.关键词
