An anchor system is used as a load carrying element for railway structure stability. The conventional systems with ground anchors bring about the anchorage loss of wedges when anchors are installed for the support of soil structures. Hence we developed the new type of anchor system using both the spacing apparatus and spring (length 60 ㎜, diameter 6 ㎜). In this system, we can directly check the condition of wedges and PS strands and modify the problems with the slip and anchorage of wedges under construction. For demonstrating the superiority of this system, we carried out a series of both laboratory and railway field test. Consequently, we can obtain satisfactory result (18.99% reduction to the loss of conventional systems). Moreover, the replacement of wedges is easy and simple when retensioning of strands.
