摘要
以广州宏城广场项目基坑工程为背景,在确保地铁安全运营的前提下,为加快工程进度,利用钢骨混凝土的特点,以组合型钢作为钢骨的外包混凝土斜撑代替钢筋混凝土斜撑,通过施工过程的整体结构模拟分析,基坑支护变形在地铁保护的限值范围内,实施效果显著,该方案具有明显的经济性和可靠性优势,对同类工程有借鉴意义。
Based on foundation pit engineering of Guangzhou Hongcheng plaza, under the premise of the regular metro operation, steel reinforced concrete diagonal braces are applied to supporting piles instead of the traditional material reinforced concrete for speeding up the progress of the project. A FEM model is established to analyze the shape and the internal force of the overall structure. The results are up to the requirements. Implementation of the effect is significant. The program has obvious advantages of economy and reliability. It has referential significance for the further similar projects.
