摘要
随着经济的发展,建设国际化大都市需要,西安地区超高层建筑越来越多。西安地区地貌单元多,地基土层差别大,对超高层建筑地基处理影响大。以西安地区工程为例,分析不同地貌单元、不同地基土层场地,桩的应力随桩身分布变化,桩身地基土层侧摩阻力随桩顶荷载增加沿桩身发挥程度不同及沉降量随时间变化分析,总结了工程经验,为今后类似工程建设提供参考。
With the development of economy and the need of building an international metropolis,there are many super high-rise buildings and geomorphic units in Xi’an area,and the difference of foundation soil layer is big,which has great influence on the foundation treatment of super high-rise buildings.Taking the project in Xi’an area as an example,the paper analyzes the variation of pile stress with pile body distribution in different geomorphic units and different foundation soil sites,the variation of shaft friction along the pile with the increase of pile top load and the variation of settlement with time.The engineering experience is summed up,so as to provide reference for similar engineering construction in the future.
