This article presents a mathematical model for simulating the mechanical behaviour of lightning strikes and analysing the resulting damage to the *** article focuses on the electro-thermal effect and seepage caused by lightning strikes in ***,a numerical model based on the conservation laws of momentum,mass and energy is developed for soil subjected to lightning *** to field observations and theoretical calculations are used to demonstrate the efficacy and accuracy of numerical *** findings demonstrate that lightning strikes can cause soils to experience both seepage force and heat *** the calculative condition of this article:by increasing the intrinsic permeability of the soil,k_(p)(≥10^(-10)m^(2)),the seepage force can be effectively reduced,hence reducing the risk of lightning strikes;improving the electrical conductivity of the soil β(≥10^(-1) S/m^(2))and lowering its thermal expansion coefficient(≤10^(-6)K^(-1))can greatly reduce the damage caused by lightning strikes to the *** preceding investigations demonstrate that the suggested model is capable of evaluating mechanical damage caused by lightning in the soil,and the findings contribute to a better understanding of soil mechanical response to lightning strikes.
