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。
The rock anchor pile foundation is not suitable for the strong weathering area and the anchor pile creep and so on. By studying its mechanical characteristics and combining with the real-type test, the foundation of the rock-bottoming anchor pile is proposed and used. The lower part of the foundation anchor pile adopts the expanded bottom type and the upper part adopts the technology of winding anchor bolts, which can effectively reduce the development of rock fracture and reduce the displacement of the rock anchor pile, so that it can be applied to the whole broken Weathered, strong weathering rock area, expanding the scope of the application of rock anchor pile foundation for future applications in other projects provided a reference.
