Development of survey system for damaging factors of road structure by TLAM system.

结构寿命取决于大体结构元素的物理完整性的保持。因此，对整个结构进行适当的检查、维护和维修程序是必不可少的。现有道路结构的破坏模式多种多样。基于各种模式的损伤检测结果进行损伤综合评估的过程十分复杂，研究成果如下：1.完成了影响结构寿命的损伤因素监测系统。2.建立了基于交通荷载自动测试数据系统的损伤构件工作应力谱分析系统。3.完成了由道路结构、钢筋混凝土、钢结构和组合结构的修复构件和部件组成的更新结构的静态和动态运动仿真系统，从而使损伤结构的养护系统更具实用性。

The structure lifetime depends on preservation of the physical integrity of gross structure element. Therefore, an adequate inspection, maintenance and repair procedure for the entire structure are indispensable. The existing road structures have various damage patterns. The integrated evaluation process of damage based on the damage inspection result of various patterns is very complex.The research results are next items.1.Surveying system of damage factors effected structure lifetime was complete.2.Spectral analysis system of working stress of damaged structural elements based on Traffic Load Auto Measuring data system was assembled.3.Statical and dynamical motion simulation system of renewal structures consist of repaired elements and parts of road structures, reinforced concrete, steel and composited strucures was completed.By above results, Caring System of Damaged Structures was more useful.
