摘　　要：指出在桥涵接长施工前必须对施工可能影响路基稳定的线路进行加固,鉴于此,介绍了线路安全防护加固方法的构造特点,并对科学的检算方法作了深入探讨,通过理论计算,验证了防护桩设计的合理性。Researchers point out that before the jointing in length construction of bridge and culvert, it must to get reinforcement on line which may have influences on subgrade stability, introduce the structural characteristics of line safety protection and reinforcement methods, and discuss the scientific check calculation methods deeply, based on the theory calculation, verify the rationality of fender pile design.

关 键 词：既有桥涵 接长施工 挖孔桩 理论检算
