上世纪90年代以后,我国高等级公路建设方兴未艾,由于缺乏对防护技术的系统研究,很多路段出现路基垮塌,如沈大高速公路鲅鱼圈所以南180km长的路段,后期的工程防治费用占整个工程防治费的80%,造成了巨大经济损失和不良社会影响。进入21世... 上世纪90年代以后,我国高等级公路建设方兴未艾,由于缺乏对防护技术的系统研究,很多路段出现路基垮塌,如沈大高速公路鲅鱼圈所以南180km长的路段,后期的工程防治费用占整个工程防治费的80%,造成了巨大经济损失和不良社会影响。进入21世纪以来,我们贵州省的高等级公路边坡防护做了许多实验性尝试,采用了多种防护修建技术,基本达到了预期防护效果。 展开更多

The lack of proper maintenance in buildings is responsible for various anomalies, which can cause property and personal damage. The objective of this study is to analyze the maintenance management of the administration building at the Technological Park UFRJ/Brazil, trying to emphasize the relation between maintenance and good performance of the building and to demonstrate the need to develop a consistent maintenance system to achieve an efficient maintenance management. The study allowed to present strategies and possibilities of interventions, in addition to proposing the essential aspects for the development of a structured maintenance system. After reviewing the issue of building maintenance under the various perspectives presented, the importance of planning a preventive building maintenance, according to standards, to achieve the level of performance expected for the building, besides being essential the search for tools and methods that can increase the efficiency of management can be concluded. It is also pertinent to conclude that prevention is the most effective solution against the depreciation factors that affect a building, being the most economical viable, and ensuring other benefits for the building and its users, such as security, property valuation and attendance to the warranty period. 展开更多
