Abstract

Structural inspection often requires slowing down the traffic during the operation by limiting the number of passing vehicles or deviating the traffic. One of the possible inspection techniques is by laser scanning. Because of the high cost of use and data treatment, the laser technique is mainly applied either in specific structures or structures with a specific behaviour. The fact that all the huge number of measurements collected by laser would not be needed, can also discourage structure owners to invest in this measurement technique for the common inspection. This paper presents an easy-to-use method for structural inspection to monitor its behaviour during the service life. A data processing method is hence suggested by adjusting a reference plane to the structure area, meshing the structure with a grid depending on the model accuracy and creating an interpolation surface applying the Kriging procedure. Two case studies were presented to illustrate the accuracy of the method and its feasibility on large structures.

摘要

结构检查通常要求在操作过程中通过限制过往车辆的数量或偏离交通量来减慢交通量。可能的检查技术之一是通过激光扫描。由于使用和数据处理的高成本，激光技术主要应用于特定结构或具有特定行为的结构。不需要激光收集的所有大量测量值的事实，也可能使结构所有者不愿投资这种测量技术进行常规检查。本文提出了一种易于使用的结构检查方法，以监视其在使用寿命期间的行为。因此，建议通过将参考平面调整到结构区域来提出一种数据处理方法，根据模型精度将结构与网格划分网格，并应用克里格过程创建插值曲面。提出了两个案例研究，以说明该方法的准确性及其在大型结构上的可行性。
