摘要:建筑施工具有多工种、多工序、立体交叉、连续作业的特点,因此也决定了其施工过程中隐藏着多种不安全因素针对目前建筑施工现场安全综合评价分析方法的配合性差、综合评判的科学性不强,评价指标反应的内容不全面和不准确等问题,并考虑到建筑施工现场综合安全评估指标体系中评价指标含义面广、交叉性和模糊性强,以及建筑施工的特殊性,本论文基于灰色欧几里德理论对建筑施工现在安全管理进行评价研究。71805
本文通过对建筑施工现场的危险因素分析和总结,从人、机和环境这个结构分析,把建筑施工现场的危险因素总结为五个方面。人的因素、设备因素、管理因素、技术因素和环境因素。并同时在对这五个方面其下的一些影响其安全程度的指标进行分析和统计。本文以此为基础建立的建筑施工现场安全评价指标体系。然后参考相关科研成功和专家的建议,运用区间层次分析法对其中的每个指标进行比较并赋值,建立相对应的区间判断矩阵。然后利用特征根法对区间矩阵进行计算并得出每个指标所对应的权重。之后利用新改进的安全检查表对该建筑工地的指标通过专家进行打分,把打分结果进行汇总。然后在利用公式计算出灰色加权关联度。并对关联度的大小和权重的大小进行分析。通过分析权重的大小和关联度大小去找出该工程的安全隐患之处,并相对应的提出一些针对性的措施,希望可以通过一些安全措施去提高该工程的安全程度。

Safety Assessment of a Construction Site Based on Gray Euclidean Theory
Abstract:The construction of the building has the characteristics of multiple types of work, multi-process, three-dimensional cross, continuous operation, and therefore also determines the construction process hidden a variety of unsafe factors for the current construction site safety comprehensive evaluation and analysis methods of poor compatibility, comprehensive evaluation of science The evaluation index is not comprehensive and the indicators are not comprehensive and inaccurate and other issues, and taking into account the construction site safety assessment index system in the evaluation of a wide range of indicators, cross and fuzzy, and the particularity of construction, the Based on the gray Euclidean theory, this paper evaluates the current safety management of construction.
Based on the analysis of the risk factors of the construction site, this paper summarizes the risk factors of the construction site from the five aspects of manpower, machinery and environment. Human factors, equipment factors, management factors, technical factors and environmental factors. At the same time in five aspects of its impact on a number of security indicators were analyzed and statistics. This paper is based on the construction safety evaluation index system. Then, with reference to the relevant scientific research and expert opinions, the interval hierarchy analysis of these indexes is compared and allocated, and the corresponding interval judgment matrix is established. The eigenvalue method is then used to compute the spacing matrix and derive the weights corresponding to each index. And then through the experts on the construction site construction site of the new improved safety checklist to score, sum up the results. And then use the formula to calculate the gray weighted correlation. And size correlation and weight analysis. By analyzing the size and extent of the weight to understand the project's security risks, so as to put forward some targeted measures, hoping to improve the safety of the project through a number of security measures.
