摘　　要：压力分散型回收式锚索是由若干个单元锚索组成 ,该类锚索可以有效调用地层强度 ,显著提高锚索的承载力 ,并能在其使用功能完成后实现对锚索体的全部回收。本文通过现场试验 ,对该类锚索的传力机制和工作特性进行了研究 。Compression-dispersion removable anchors involves the installation of several unit anchors into a single borehole,which can efficiently mobilize the in-situ ground strength and increase the anchorage capactiy,and can be removed from the borehole after the usage for the total length.Based on the field tests,the distribution of strain in the fixed length of two units and the anchorage performance of the said anchors are studied,and the design and construction of the anchors are discussed.
