Abstract

Background:

Based on the routine inspection of 637 simple-support bridges in a severe cold region in northeast China, the technical condition data were collected and analyzed according to China’s bridge condition evaluation code.

Results and Discussion:

The results indicate that the appraisal rating of the bridges decreases with service time gradually. For bridges with a service life of 3-5years, 7 years and more than 15 years, the proportion of rating of “poor condition” is 14%, 22% and 43%, respectively. Besides, the inspection results show that cracking, concrete scaling, and corrosion of reinforcement are the major damage types of the bridges, and the freeze-thaw and salt induced corrosion are the main deterioration causes. It is recommended based on the inspection results that timely drainage of water is very important in reducing bridge damages in severe cold regions. Meanwhile, protective measures of durability should be specially considered in the design and construction stages.

Keywords: Bridge, Technical condition, Northeast severe cold region, Damage, Maintenance, Appraisal.

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."
