摘要
结合具体工程实例,分析"土钉喷锚+混凝土灌注桩+预应力锚索+钢管内支撑"支护形式在地铁车站明挖基坑支护应用中的特点及原理,论证了地铁车站深基坑采用复合围护结构的可行性,同时也阐明了施工过程中的控制要点、与一般围护结构性能的对比。
Combined with specific project example,this paper analyses the feature and principle of ＂soil-nail sprayed anchor and cast-in-place concrete pile and prestressed anchor cable and steel tube inner bracing＂ supporting style in the foundation pit support of open-cut metro station,discusses the possibility of the applying complex retaining structure in metro station deep foundation pits and elaborates on the key controlling points and its performance comparison with ordinary retaining structures in the construction course.
