| 摘 要： | 介绍了现浇薄壁筒桩技术，并以实测资料为基础分析了单桩及复合地基受力特性。现场试验研究表明，沉管灌注筒桩竖向承载性能好，同时由于大直径所产生的薄壳效应能够提供较大横向抗力，筒桩复合地基在沉降和承载方面均能够很好的满足工程需要，更具有质量可靠，造价低廉等优点。

| Abstract: | Cast-in-place tubular pile technology is introduced. Based on the in-situ test data, the engineering property of single pile and composite foundation are specially analyzed. It is found that the cast-in-place tubular pile gives prominence to its vertical bearing capacity. At the same time, the pile can have large diameter which induced thin-shell effect that enable the pile with high horizontal resistance. Finally, the tubular composite pile foundation test indicates that it not only well meet engineering requirement in settlement and bearing capacity, but also has the advantages of good quality, low cost etc. |
