The reinforced technique of pre-stressed fibre cloth is a renovation to traditional reinforced method of affixed fibre cloth.It can fully bring the fibre cloth with high intensity into play,and improve the performance of reinforced concrete structure in the extreme.The key to realization of pre-stressed fibre cloth is the reliable anchorage mode an convenient tension method.A simple and feasible method and a new design theory of pre-stressed fibre cloth are brought forward.It can be applied in engineering practice.
