模数式大位移伸缩缝智能监测

摘要:

通过对模数式大位移伸缩缝的构造特点分析和运营现状调研,橡胶类部件性能劣化引起变形协调系统与中梁稳定系统的失效,最终导致竖向力传力系统损坏,是伸缩缝破坏的主要原因。通过对中梁各缝宽的监控及分析能够有效反映伸缩缝易损构件的使用状况,利用远程技术数据采集,经分析后做异常缝宽的检修预警,能够有效避免伸缩缝的结构性损坏。

Abstract:

Based on the analysis of the structural characteristics and the investigation of the operation status of the large modular expansion joints, the deterioration of the performance of rubber components leads to the failure of the deformation coordination system and the beam stability system, and finally leads to the damage of the force transmission system, which is the main reason for the damage of the expansion joints. The monitoring and analysis of the width of the beam can effectively reflect the use of vulnerable components of joints. The use of remote technical data collection and analysis can effectively avoid structural damage to the expansion joints.
