第一章前言导弹地下井是钢筋混凝土和钢制结构,其作用在于保护处于战备状态的陆基战略洲际弹道导弹避免核攻击的破坏。弹道导弹通常不能承受较大的垂直于弹体对称轴的载荷。弹道导弹携带各种精密的电子器件,这些器件很容易被意外的较大冲击载荷和/或强电磁脉冲或强核辐射所毁坏。因此,洲际导弹如果部署在不加防护的地面发射台上,就很容易被敌方先发 Chapter I Foreword Missiles Underground wells are reinforced concrete and steel structures whose role is to protect land-based strategic ICBMs in readiness to avoid nuclear damage. Ballistic missiles are generally not capable of withstanding large loads perpendicular to the axis of symmetry of the projectile. Ballistic missiles carry sophisticated electronic devices that can easily be damaged by accidental large shock loads and / or strong electromagnetic pulses or strong nuclear radiation. Therefore, intercontinental missiles if deployed in the unprotected ground launch pad, it is easy to be the enemy first
