摘要
针对地下建筑物遭受雷击损害的风险难以确定的问题,分析了地下建筑物遭受雷击的原理,给出了雷电损害地下设施及线路的途径以及地下建筑物及交通设施遭受雷电损害的来源。给出了一组可以作为地下建筑物雷电灾害风险评估的风险因子。指出埋地电缆的接地点数量,电缆的埋深,光缆的接地方式可以作为评估其雷击风险的因子。
To solve the problem that risk of lightning determine, the theory of lightning to underground buildings lightning damage damage to underground buildings is hard to was analyzed, and the possible ways that the the underground installations and lines are given as well as the source of lightning damage suffered by the underground building and the traffic facilities. A group of risk factors to evaluate the lightning risk of underground buildings was given. It is indicated that the number of grounding points of buried cable, the burial depth of buried cable as well as the grounding mode of optical cable can be used as the risk factors to evaluate the lightning risk of underground buildings.
