随着城市地铁工程的规模化建设和岩土锚固技术的不断发展,预应力锚索支撑体系在地铁车站主体围护结构中得到广泛应用,新技术受地质条件的复杂性、围护结构的强度、整体稳定性和变形的影响较大,所以本文将分析预应力锚索在地铁车站明挖支撑体系防护中的特点及原理,提出了预应力锚索结构的构造要点,阐述了锚索支护应用的施工技术要点及施工工艺。
With the large-scale construction of urban subway project and the continuous development of rock and soil anchoring technology, the prestressed anchor cable support system has been widely used in the envelope of the metro station main body. The new technology is affected by the complexity of geological conditions, the strength of the envelope , The overall stability and deformation of the impact of a large, so this paper will analyze the prestressed anchor cable in the metro station Ming dredging support system protection features and principles, proposed prestressed anchor cable structure points, elaborated the anchor cable support Application of construction techniques and construction techniques.
