| 中文摘要: |
| 市政道路工程通常以下穿、伴行等形式侵入临近轻轨高架桥结构的影响范围内，针对管沟开挖、路基铺设等限制性施工活动，必须进行施工影响评估。本文依托某市政道路施工下次轻轨高架桥工程，采用有限元建模分析方法，利用 MIDAS-GTS软件建立三维模型，依据施工次序设置计算工况，分析新建道路管线施工对轻轨高架桥结构变形的影响。通过合理布设结构变形监测措施，一方面提高轻轨高架桥结构安全保障，另一方面验证有限元分析评估结果，为不断提高评估准确度和指导施工作业提供参考。 |

| Municipal road projects usually under the form of penetration, accompanying and other forms of in-trusion into the adjacent light rail structure within the scope of influence, for pipe trenching, roadbed paving andother restrictive construction activities, must be carried out construction impact assessment. This paper analyses theimpact of the construction of new road pipelines on the structural deformation of the light rail viaduct by finite ele-ment modeling analysis method and using MIDAS-GTS software to establish a three-dimensional model of someonemunicipal road construction under the light rail viaduct project. Through the reasonable deployment of structural de-formation monitoring measures, it could improve the structural safety of the light rail viaduct, and verify the resultsof the finite element analysis and assessment. It’s helpful to improve the accuracy of the assessment and to provide a reference for the construction work. |
