Abstract Full grouted prestressed anchor has characteristic of reliable auto-lock anchorage in tension section. This can reduce the prestress loss effectively，hold essential prestress value within bolt when prestress lose in its anchorage to avoid catastrophe，and improve reliability of reinforced engineering. Numerical simulation，field measurement and case study indicate its primary mechanical characteristic and reinforcing effect sufficiently.
