摘要
压力型和压力分散型抗浮锚杆已在工程中应用,但是现场测试数据的缺乏影响了其更为广泛的应用和发展。本文通过对压力型、压力分散型抗浮锚杆的原位抗拔试验,测试了其载荷—位移曲线,分析了两种抗浮锚杆的受力和变形特点,探讨了压力分散型抗浮锚杆的破坏形式,为进一步研究其工作机理提供了依据。
Compression and compression-dispersive anti-float anchor have been used in engineering, but widespread using and development are affected by lacking in-situ test data. In this paper, loading-dlsplacement curves of compression and compressiondispersive anti-float anchor are obtained by in-situ pulling test, mechanical and deformational characteristics of them are analyzed, failure patterns of compassion-dispersive anti-float anchor are probed, the basis of further research of working mechanism of it is provided.
