摘要
中原文旅城欢乐世界一期雪世界高区采用了巨型钢框架结构体系,基础形式为群桩基础,满足了基础内力大、沉降控制要求高的要求.介绍了巨型框架结构以及基础设计内力大、沉降控制要求高等特点.以中原文旅城欢乐世界一期雪世界项目滑道高区的基础设计为例,详细介绍了该工程地质概况、桩型选择、基础设计原则;进行了基桩承载力计算和验算,并分别采用YJK和ABAQUS对基础的沉降进行分析.其中ABAQUS模型考虑了桩、土、承台的相互作用,克服了传统计算方法不能细致分析桩身弹性压缩、实体深基础侧阻力和应力扩散等的不足.
Abstract
The giant steel frame steel structure system is adopted in high area of Zhongyuan Cultural and Tourism City Happy World Phase Ⅰ,and the foundation form is a group pile foundation,which meets the requirements of large internal force of the foundation and high settlement control requirements.Taking the foundation design of high area of Sunac Zhongyuan Cultural and Tourism City Happy World Phase Ⅰ Project as an example,the geological situation,pile type selection,and foundation design principles were introduced in detail.The calculation and verification of pile bearing capacity of foundation were carried out,YJK and ABAQUS were used to analyze the sedimentation of the foundation respectively.The ABAQUS model considers the interaction of piles,soil and caps,which overcomes the shortcomings of the traditional calculation method that cannot carefully analyze the elastic compression of the pile body,and the lateral resistance and stress diffusion of the solid deep foundation.
