Abstract: The small radius curved bridge (also known as curved bridge) has become an important bridge type in modern traf c engineering. Compared with the straight bridge type, the reaction force of curved bridge has the trends of the outer bearing force becoming bigger and the inside bearing force becoming smaller, and even the inside bearing
