Rehabilitation of Prestressed Concrete Bridge Components by Non-Electrical211 (Conventional) Methods

摘要

The objectives of this study were: (1) to perform a detailed review of technology211u001erelating to corrosion-induced and other deterioration in PS/C bridges; (2) to 211u001eidentify a set of PS/C bridges located in various adverse environments and carry 211u001eout field condition surveys and laboratory analyses on samples obtained from the 211u001eselected structures; (3) to identify the causes for corrosion in PS/C structures 211u001ebased on analysis of collected field and laboratory data; and (4) to evaluate the 211u001eeffectiveness of rehabilitation techniques commonly used to extend the service 211u001elife of PS/C bridges.
