A Survey on Project Application of External Prestressing Technology

This article mainly introduce the major effect factor of external prestressing technology, for instance: The reasonable external prestressing’s transmission system chiefly includes two aspects of prestressing size and prestressing function position; The tendon steering system is to solve the centralized solution of local stress and the grasp stress of weak link ; The external prestressing anchor system must guarantee multiplicity and construction security; In construction monitoring process，it must grasp the monitor parameter of the prestressing and the deflection and so on; The anti-vibration localization of the external prestressing is to enhance the structure durability etc., which have provided the advantageous technical guidance for the actual projects.
