Anchor of concrete blocks for application to sea dike slope

Abstract

    Protected slope by interlocking units (concrete blocks and mats) is popular types of revetments. However, instability of interlocking units still occurs near the point of maximum downrush, where uplift forces are higher or wave impact. Anchor of concrete blocks is a new choice of protection, higher resistance against uplift and reducible displacement of revetments. Anchor of concrete blocks has three essentially parts: anchor head, tendon and fixed anchor. The anchor head is made from plastic with twisted slot. High tensile plastic cable is used for tendon. Fixed anchor is connected to concrete blocks. The number of anchors depend on weight of concrete blocks, wave forces and dike funtion. This paper is results testing for allowable pull of anchored concrete blocks in the Geo-laboratory of WRU Vietnam.
