摘要
为提高山岭隧道施工场地安全布局水平,以牛栾村隧道施工场地为例,提出一种改进的系统布置设计(SLP)法,布设混凝土拌合站、机械库房、水泥库等13个单元场地,将该方法与贝叶斯网络模型结合,通过对比建筑施工场地布置影响因素,确定山岭隧道施工场地布置的重要因素权重和布设单位间的综合相互关系,形成2种场地布置优化方案,并通过建立数学模型,以安全水平强度、材料流动强度和运输时间为目标函数,结合因素加权法对比优化方案与原方案,确定相对最优场地布置方案。结果表明:改进SLP法得出的最优场地布局方案相比于原方案,改动区域较小,且在安全水平强度、材料流动强度和运输时间上提高12.30%。该方法有助于提高山岭隧道施工效率,增强施工场地安全水平。
In order to improve the level of safety layout of the construction site of the mountain tunnel,taking the construction site of Niuluan village tunnel as an example,an improved SLP method was proposed to lay out the site for 13 units such as concrete mixing station,machinery storehouse,cement storehouse,etc.The method was combined with a Bayesian network model,and the weight of important factors of the site layout of the mountain tunnel was determined by comparing the factors influencing the layout of the building construction site and the comprehensive interrelationship between the laying units,forming 2 site layout optimization schemes,and determining the relative optimal site layout scheme by establishing a mathematical model with safety level intensity,material flow intensity and transportation time as the objective function,and comparing the optimization scheme with the original scheme by combining the factor weighting method.The results show that the optimal site layout scheme derived from the improved SLP method is smaller than the original scheme in terms of the altered area,and improves 12.30%in terms of the safety level intensity,material flow intensity and transportation time,which helps to improve the efficiency of mountain tunnel construction and enhance the level of construction site safety.
