摘　　要：通过新建天津—秦皇岛铁路客运专线四标段沙河特大桥连续梁段54号桥墩基坑支护选用支护桩方案实例,对支护桩进行了力学计算和配筋、抗滑检算,施工实践表明,该支护方案方便可行,有效地保护了既有线路基的安全.Based on the example of NO.54 pier excavation of the continuous beam section of the extra-large bridge across the Shahe River on the Jin-Qin railway line,a mechanical calculation and reinforcement and slide checking of supporting piles have been carried out.Practice showed that the program was convenient and practical,and could effectively protect the existing circuit-based security.
