摘要
构建了一种融合ArcGIS核密度分析与层次分析法(AHP)的综合性建筑工程风险评估方法,旨在显著提升施工区域的安全性。该方法通过建立空间模型,利用ArcGIS系统对机械设备、施工环境与人员风险等多种因素进行地理分布分析,并引入相邻点平均距离的核密度分析策略,以优化高风险区域识别的精准度。结合AHP赋予各风险因素的权重,研究结果显示,该方法能够动态且高效地识别高危区域,并提供智能化的决策支持。研究创新体现在对相邻点平均距离经验法的应用,强化了方法对局部密度变化的敏锐度,使其能够满足动态施工环境中对风险精细化控制的要求。本方法为建筑安全管理提供了先进的空间评估手段和可靠的数据支持。
A comprehensive risk assessment method for construction engineering was developed by integrating ArcGIS kernel density analysis with the Analytic Hierarchy Process(AHP),aiming to significantly improve the safety of construction areas.The proposed method established a spatial model that utilizes the ArcGIS system to analyze the geographical distribution of multiple risk factors,including mechanical equipment,construction environment,and personnel risks.Kernel density analysis based on the average distance between neighboring points was introduced to optimize the accuracy of high-risk area identification.Weights were assigned to each risk factor using AHP.The results indicate that the proposed method can dynamically and efficiently identify high-risk areas and provide intelligent decision support.The innovation of this study lies in the application of the average distance between neighboring points,which enhances sensitivity to local density changes and meets the requirements for refined risk control in dynamic construction environments.This method provides advanced spatial assessment tools and reliable data support for construction safety management.
