本文针对地下工程平面模型简化方法存在的问题,对某沿海城市地下人防工程建立空间计算模型,揭示空间计算模型结构所受内力小于平面简化模型,且空间模型理论更接近于实际工程,有一定的优越性。此外,还讨论了外墙不同影响因素下内力变化规律,最后对地下室外墙受力特点进行了总结。
In this paper, aiming at the problems existing in the simplification of underground engineering plane model, a space calculation model is established for underground civil air defense works in a coastal city. The results show that the internal force of the spatial calculation model structure is less than that of the plane simplified model, and the spatial model theory is closer to the actual project. Superiority. In addition, the internal force variation under different influence factors of the external wall is also discussed. Finally, the stress characteristics of the external wall of the basement are summarized.
