摘要:
为解决管廊或管沟内的电缆敷设密度较大，发生火灾极易形成电力系统的连锁事故等问题，采用FDS仿真软件，综合考虑传感器、喷淋系统、通风系统和防火门等安全屏障不同响应情况构建管廊电缆火灾动态风险评估模型，并应用Arrhenius公式将数值仿真结果指标映射为电缆火灾风险值，进而绘制时变的电缆火灾风险曲线，探究火灾情景下管廊电缆风险动态评估及应急决策优化方案。研究结果表明：喷淋系统是管廊电缆火灾风险的最关键影响因素，喷淋系统的安装位置以及动作状态在很大程度上影响管廊电缆火灾风险。研究结果可为地下管廊电缆线路典型事故的预防、处理和恢复提供应用价值。
Abstract:
In order to solve the problem that the cable laying density in the utility tunnel or pipe trench is large,and the fire is easy to form a chain accident of the power system,the FDS simulation software was used to construct a dynamic risk assessment model of cable fire in the utility tunnel with comprehensively considering the different response of safety barriers such as sensors,spray system,ventilation systems and fire doors.The Arrhenius formula was used to map the indexes of numerical simulation results into the risk value of cable fire,and then the time-varying risk curve of cable fire was drawn to explore the dynamic risk assessment and emergency decision optimization scheme of the utility tunnel cable under the fire scenario.The results show that the spray system is the most critical factor affecting the cable fire risk of utility tunnel,and the installation position and action state of the spray system greatly affect the cable fire risk of utility tunnel.The research results can provide application value for the prevention,treatment and recovery of typical accidents of cable lines in underground utility tunnel.
