摘要
岩石锚桩基础存在不适用于强风化地区且锚桩蠕变等问题,通过研究其力学特点并结合真型试验,提出并使用了岩石扩底锚桩基础。该基础锚桩下部采用扩底型式,上部采用缠绕锚杆的技术,在提高承载力的同时,还有效减缓岩石裂隙的发展,减小岩石锚桩的位移,使其能够适用于较破碎的全风化、强风化岩石地区,扩大了岩石锚桩基础的适用范围,为今后在其他工程的应用提供了参考。
In this paper, for solving the adaptability and rock creep of foundation using in strongly weathered areas, the belled rock-anchor pile foundation is proposed and applied on the basis of the mechanical characteristics and loading test. The enlarged pile bottom and upper winding anchor technology are used for expanding the scope of application. In addition, the foundation can improve the bearing capacity, effectively slow the development of rock fractures and reduce the displacement of the rock anchor pile, providing references for similar projects.
