基于随机游走算法的建筑工地人员施工通道安全优化设计

Safety Optimization Design of Construction Passage for Construction Site Personnel Based on Random Walk Algorithm

首先,根据建筑工地事故统计数据评定各工种人员在各种施工环境中的风险量化指标。其次,考虑施工现场各风险源与障碍区域,以随机游走算法为工具,进行建筑工地人员施工通道选线优化设计。在优化设计中,优化变量为施工通道几何位置;优化目标函数设定为全体施工人员沿施工通道累积风险量化指标;约束条件设定为建筑工地施工范围、禁区、障碍物区域以及出入口位置。最后,应用随机游走算法对某建筑工地现场进行施工通道安全优化设计,使得全体施工人员风险量化指标最小化。

Firstly,according to the statistical data of construction site accidents,the risk quantification index of each type of workers in various construction environments is evaluated.Secondly,considering each risk source and obstacle area on the construction site,the random walk algorithm is taken as the tool to optimize the design of construction passage selection for construction site personnel.In the optimization design,the optimization variable is taken as the geometric position of the construction passage;the optimization objective function is set as the quantitative index of the accumulated risk of all construction personnel along the construction passage;the constraint conditions are set as the construction scope,forbidden area,obstacle area and entrance and exit positions on the construction site.Finally,the random walk algorithm is used to optimize the safety design of the construction passage on the construction site,so as to minimize the risk quantification index of all construction personnel.
