摘要
对美国费城自由广场一号塔楼下的Ｇ一１０号嵌岩桩（８．８ｍＸ２．６～３．０ｍ，设计荷载５３８４９ｋＮ）在成桩后数月及上部结构施工期间和竣工后成功地进行了荷载传递性状的连续观测。本文介绍该桩的地质条件、桩身埋设的量测元件以及历时两年半的观测成果。观测表明，该桩在不同荷载水平下桩顶荷载的６０％～７０％始终由桩侧阻力分担。这一成果与第一作者先前根据嵌岩桩静载试验结果作出的结论相吻合。
A continuous observation is taken of theloading transmission of G-10 rock-inlaying pile ( 8.8m×Φ2.6～3.0m,designed loading 53849 KN)un-der the No.1 Tower of Freedom Square,U.S.A.af-ter several months of the completion of pile,andduring the construction of above stucture as well aswell as after the completion of completion. The au-thors introduce the geological condition of the pile,measuring elements of pile burial and the obserua-tion results of 2 and a half years.The obervation re-veals that 60%～70%of the lateral rssistence at dif-ferent loading level. The result coincider with thatof the static loading test done by the first author.
