建筑施工区域风险研究

根据国内建筑施工过程现状和作业特点,以及国内外学者对建筑施工过程中风险的研究,考虑到建筑施工区域不但面临单体建筑施工的各种风险,还必须克服单体施工过程中时空上相互干扰而带来的风险,构建了单体建筑风险分析模型、确定单体建筑风险的影响梯度、提出建筑施工区域总风险计算方法。示例分析表明,该风险分析模型和计算方法,可以全面系统地预测区域内风险的分布及其变动情况,有助于实施有针对性的风险预防和控制措施,有益于提高建筑施工区域全过程的安全管理水平。

Study on Risks in Building Construction Area

According to the status of domestic construction process and its working features and the studies on construction engineering risks by scholars all over the world, and taking into consideration the fact that workers in construction area face both the risks from single building construction and the ones from the multi-interference in time and space between them during working process, the risk analysis model for single building and its influence gradient, and the risk calculation method for the total risk of construction area are presented. An application example demonstrates that the model and the calculation methods can be used to predict the distribution and changes of the risks in construction area. This study is helpful to the risk prevention and the implementation of controlling measures, as well as the improvement of safety management level in entire process of construction.
