谏壁船闸系统设施预应力土层锚杆技术应用研究

Research on Application of the Prestressed Earth Mooring Rod Technique Adopted in Jianbi Shiplock Mooring Device

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。

Based on the site test and observation data for earth mooring rod adopted in construction of mooring device of Jianbi Shiplock approach channel, it analyzed and studied several problems in application of earth mooring rod such as limit bearing force, force endured by the moored section of earth mooring rod, as well as the prestress loss of earth mooring rod. Some problems needing attentions in design and construction of earth mooring rod are pointed out.
