Should make the anchor and insert one and stranded wire surface hardness standard, so as to ensure the anchorage has anchor complete.
应制定锚具央片与钢绞线表面硬度标准，以保证锚具锚固安全。

As an advanced post installed anchorage technology, insert rebar has already been applied to civil structural engineering all over the world, and has vast prospect for using in protected engineering.
Time history curve and space curve of the dynamical strain and bond stress of insert rebar with different anchorage length and loading conditions were gained.
