摘要
水泥搅拌桩加固技术是滨海软土地基处理最常用也最有效的方法之一.充分掌握水泥固化滨海软土的动力特性及其动态演化规律,是确保水泥搅拌桩软土地基在密集地铁线网和持续波浪作用所产生的动力荷载下维持安全稳定的重要前提.本文对当前国内外水泥固化滨海软土的动力特性和本构模型进行综述,系统归纳和分析水泥固化滨海软土的动力试验类型、动力特性指标、动力本构模型以及动力特性优化方法,讨论当前水泥固化滨海软土动力特性研究的不足,探讨具有针对性的研究建议,为水泥土动力特性研究提供新的思考和思路.
Abstract
Cement mixing pile reinforcement technology is one of the most commonly used and effective methods for coastal soft soil foundation treatment.Fully grasping the dynamic characteristics and dynamic evolution laws of cement solidified coastal soft soil is an important prerequisite to ensure the safety and stability of cement mixed pile soft soil foundation under the dynamic loads generated by dense subway network and continuous wave action.A review is conducted on the dynamic characteristics and constitutive models of cement solidified coastal soft soil both domestically and internationally.The dynamic test types,dynamic characteristic indicators,dynamic constitutive models,and optimization methods of cement solidified coastal soft soil are systematically summarized and analyzed.The shortcomings of current researches on the dynamic characteristics of cement solidified coastal soft soil are discussed,and targeted research suggestions are explored,which may provide new thinking and ideas for the study of the dynamic characteristics of cement soil.
