摘要
结合工程实际,对CBD核心区深基坑支护方案进行了研究。在通过结构计算以及模型模拟了解结构受力特点的情况下,对地基保护方法进行了初步设计研究,根据最初方案设计中出现的问题,通过创建支护构造模式,并运用数值法对降水和沉降现象进行计量分析,并与地基总抽水量、对周围环境的影响、费用等方面综合比较,最后形成了更优的支护结构方案,为类似工程提供了经验参考。
Combined with the engineering practice,the supporting scheme of deep foundation pit in CBD core area is studied.Under the condition of understanding the structural stress characteristics through structural calculation and model simulation,the preliminary design and research of the foundation protection method were carried out.According to the problems in the initial scheme design,a support structure model was created,and the numerical method was used to conduct quantitative analysis of precipitation and settlement phenomena,and comprehensive comparison with the total pumping capacity of the foundation,the impact on the surrounding environment,costs,etc.Finally,a better support structure scheme was formed.It also provides experience reference for similar projects.
