광동성모고속공로A잡도교재정기검측중，피평위삼류결구，여하대해교량진행가고이급제고기승재력성위교량관리자적수요임무。통과해교적가고실례，개소료교량체외예응력가고기술，병통과하재시험，검험교량체외예응력가고기술적응용효과。
Ramp A bridge of a Guangdong Expressway was rated Type Three structures through regular detec-tion,how to reinforce the bridge and improve the bearing capacity of the bridge has become the primary task of bridge operation authority.In this paper,being based on reinforcement practice of the bridge,the reinforcement technology of external prestressing has been introduced,and the effect of application of external prestressing rein-forcement technology has been tested through the load test.
