从谏壁船闸引航道系缆设施工程中采用的土层锚杆的现场试验、观测资料入手，对人们在土层锚杆应用中普遍关心的极限承载力、土层锚杆的锚固段受力状态、土层锚杆的预应力损失等问题进行了分析与探讨。并指出土层锚杆设计与施工中值得注意的一些问题。 From the site test and observation data of soil anchor used in the construction of mooring line guideway of Jianbi Lock, the ultimate bearing capacity of soil anchor which is commonly concerned in the application of soil anchor, the force of anchor in soil anchor State, the prestressed soil anchor bolt loss and other issues were analyzed and discussed. And pointed out some problems that should be noticed in the design and construction of soil anchor.
