摘要

    摘要
  • 摘要: 陈家祠广场地下空间工程具有开挖面积大、地质条件复杂、周边临近世界文化遗址和城市轨道交通线、工期紧等特点。立足于安全、可行、合理的设计与施工原则，重点进行了基坑围护结构方案比选分析，深入设计了以旋挖桩与内衬墙相结合的“桩墙合一”、以地下层楼盖结构为水平内支撑的逆作法围护结构。对基坑工程设计的不确定性因素进行了分析，选取支护结构变形特性的可靠度指标，运用蒙特卡洛有限元方法计算了围护结构失效概率。工程项目如期安全实施，实现了为保证 2010 广州亚运会圆满成功提出的要求，表明“桩墙合一”的逆作法方案及其各项设计参数对于陈家祠广场地下空间基坑围护工程是可行的。
    Abstract: The underground space project of Chen Clan Academy Cultural Square adjacent to world cultural heritage and urban rail transit lines is characterized by large excavation face, complex geological conditions and limited construction period. Based on the design and construction principles of safety, feasibility and rationality, different support structures for foundation pit are analyzed and compared. The top-down construction method featured with spun digging pile-lining wall interaction and basement floor system working as the horizontal interior bracing is elaborately designed. Through discussing uncertainties of the foundation pit, the reliability index on the basis of deformation of support structures is established, and the failure probability of support structures is calculated by Monte-Carlo FEM. The project is carried out safely and on schedule, satisfying the requirements put forward with the purpose of ensuring the 2010 Asian Games successfully held. It is indicated that pile-wall interaction with adverse construction as well as the relevant design parameters is reasonable and adequate to the support structures for the foundation pit of Chen Clan Academy Cultural Square.
