船台工程结构的安全性评估

对达到或超过设计使用年限、擅自提高使用功能的船台,需对其进行安全性评估,分析和论证船台的造船和大修能力。安全性评估应在现使用荷载条件下对结构构件进行复核验算,验算内容应包括结构的受力、配筋或位移变化情况,并结合现场调查和检测情况综合分析。结合工程实例对船台工程结构的安全性评估进行阐述,可作为其它结构物评估的参考依据。

Safety assessment of shipway engineering structure

For the shipway exceeding the design service life, we shall carry out safety assessment to analyze the ship-building and repairing ability of the shipway. The assessment is to conduct checking calculation of the structural members under present working load, including the stress, reinforcement or displacement of the structure,combining with the site investigation and detection to carry out a comprehensive analysis. This paper expounds the safety assessment of shipway based on an example of shipway engineering, which may serve as a reference for the assessment of other structures.
