PHC管桩目前在房建、码头、桥梁的软弱地层中逐步深入和应用。但是也有很多问题正在研究和摸索过程中,需要施工中深入总结和研究。该文章是作者在蒙华铁路金家门特大桥大直径管桩(直径1m)在施工过程中分别对直桩、斜桩、开口桩尖、闭口桩尖进行了试桩,并仔细的观察记录,通过对检测结果进行以及对大直径PHC管桩各桩型进行比较分析,为后期大直径PHC管桩在桥梁上的直桩以及斜桩应用提供参考依据。
PHC pipe pile is currently in the house construction, docks, bridges and weak layers gradually in-depth and application. However, many problems are still being explored and explored in the process, which needs to be summarized and studied in depth. This article is the author of the Mongolian Railway Jinjiamen Bridge large diameter pipe pile (diameter 1m) during the construction of straight piles, inclined piles, open piles, closed piles were tested and carefully observed and recorded, Through the comparison of the test results and the pile types of large diameter PHC pipe piles, it provides a reference for the application of straight piles and inclined piles on large diameter PHC pipe piles.
