【摘要】 门架式桩锚支护结构具有形式简单,受力明确,支护可靠,施工操作空间大,费用较低等优点,适用于场地狭窄、周围有高耸建筑物,对基坑位移要求特别严格,不能采用双排桩和桩锚方案的深基坑工程。主要从力学原理的角度分析了门架式桩锚支护结构的特点,并结合具体工程实例,详细论述了门架式桩锚支护结构的优势。更多还原

【Abstract】 Gantry pile-anchor supporting structure has the advantages of simple form,load clear,reliable support,construction of operating space and low cost.It can be applied in the deep foundation excavation of narrow space,be surrounded by tall buildings,particularly stringent requirements on the foundation displacement which cannot be applied by double piles and pile-anchor.In this article,features of gantry pile-anchor supporting structure are analyzed from the perspective of mechanics.Combined with specific examples of project,the advantages of gantry pile-anchor supporting structure are discussed in detail.更多还原
