【摘要】：随着国民经济的不断发展，城市道路建设的规模在各大城市的应用中越来越为广泛，在城市道路的施工过程中往往会存在一定的风险，严重的甚至导致路面和建筑物塌方，造成人员的伤亡和设备的损失，因此有必要建立一套完善的针对道路施工方面的安全评估以及周围建筑环境的安全评估体系。本文针以广东某地区的季华路道路施工工程为例，在总结国内外相关领域研究和发展概况的同时，结合当地的工程地质以及水文地质条件，包括地形和地貌、抗震设防强度等等，在此基础之上利用对地道路工周边的建筑物环境的安全性进行了分析。本文主要研究了以下几个问题：道路施工边坡安全评估；道路基坑开挖对周围建筑环境的影响；道路基坑回筑对周围建筑环境的影响。本文依据各种地质侦查的结果和数据，对于地道深度比较小的路段主要是采用一种水泥性质的土壤进行不断搅拌，剩下的部分采用0.6米以及0.8米厚的地下连续墙作为整个维护部分的结构。基坑均采用明挖法施工，采用连续墙-支撑基坑支护方案，保障了边坡安全；在整个地道进行施工和建设过程当中，由于重型设备在施工的同时会对地道上方不断进行装载重物和卸载重物，因此造成的后果就是对周围的建筑物设备产生比较严重的影响。本报告对整个施工过程进行仿真模拟，以掌握各个施工阶段对围建筑环境的影响。基于以上分析结果，充分考虑各种因素对周围建筑环境位移的影响，提出问题的处理方法和建议。
[Abstract]:With the continuous development of the national economy, city road construction scale and application in each big city more widely, in the process of construction of city road often there will be some risk, and even lead to serious road and buildings collapse, causing casualties and loss of equipment and personnel, it is necessary to establish a set of perfect according to the safety evaluation of road construction and building environment safety evaluation system.
This pin to a region of Guangdong Jihua road construction project as an example, in summarizes the domestic and foreign research and development of related fields at the same time, according to the engineering geological and hydrogeological conditions, including topography and geomorphology, seismic fortification intensity and so on, on the basis of this benefit was analyzed with the safety of the tunnel surrounding road the building of the environment. This paper mainly studies the following problems: road construction slope safety assessment; impact on the environment around the buildings excavation pit pit road; road to build influence on the environment around the buildings. In this paper, according to the geological investigation results and data for tunnel depth relatively small section is mainly used for cement the nature of the soil was stirring, the rest of the 0.6 meters and 0.8 meters thick underground continuous wall as the maintenance part of the structure. The foundation pit are made clear Excavation construction method using continuous wall support of foundation pit supporting scheme, guarantee the slope safety; the construction process and construction of the tunnel, because of heavy equipment in the construction of the tunnel and continuous loading and unloading above the heavy weight, so the consequences is to have a more serious impact on the surrounding buildings and equipment this report. The simulation of the whole construction process, in order to grasp the various stages of construction impact on Wai built environment. Based on the above analysis, considering the influence of various factors on the displacement of the surrounding environment of architecture, treatment methods and suggestions put forward the question.
