摘要： 桩锚支护结构在基坑工程中已有广泛应用，通过对锚杆施加一定的预应力，可使其产生的水平变形较小；通过调整锚杆的位置和层数可使支护桩内力分布较均匀；并且在基坑内形成无障碍空间，便于土方开挖运输和后期主体地下结构施工。结合金湖县中医院门诊病房综合楼基坑工程实例，简要介绍了深基坑桩锚支护结构的设计计算。

Abstract: The ground anchors combined with the piles are widely used in the deep excavation projects. The horizontal deformation of the excavated wall can be reduced if the pre-stressing is applied on the ground anchors. The number of the ground anchors and their locations can be flexibly arranged according to the deformation control requirements. The other advantage of the use of ground anchors is that the internal strutting support numbers can be reduced and working spacing inside the excavated area so that the excavation as well as the foundation construction work can be facilitated. This paper presents the design and analysis aspects of the ground anchor applications in supporting of the deep excavations of the MultiPurpose Building of the Patient Center for Chinese Medicine Hospital of Jinhu County.
