刚柔复合桩承载行为的施工与界面效应:研究现状与展望
Interface effect and bearing performance of rigid-flexible composite pile:Research status and prospects
摘要
Abstract
Soft soil ground has large deformation and low strength.In engineering practices,pile-supported composite ground is often used for the improvement.Among them,the rigid-flexible composite pile ground is widely adopted due to its strong load-bearing and settlement control efficiency and the low construction cost.Firstly,this paper introduces typical composite methods and the construction process for the rigid-flexible com-posite piles in China.Secondly,the representative composite pile,that is,the pile combining inner-core high-strength(reinforced)precast concrete pipe piles with outer-core cement-soil mixing piles,was concen-trated,where the construction effect,multi-interface interaction,and load-bearing characteristics were empha-sized.After an international literature review,the effects,including the squeezing soil and squeezing pile ef-fect,coaxial effect,and multi-interface effect,design methods of compressive and uplift bearing capacity,and settlement calculation for the rigid-flexible composite piles were systematically summarized and analyzed.Finally,the future research and technical countermeasures of the composite piles in the pile squeezing effect,coaxial effect,and horizontal bearing capacity design,etc.,were pointed out,which provides a reference and basis for the development and engineering application of rigid-flexible composite pile technology.关键词
