防护工程是国防威慑力量的重要组成部分，具有重要的战略地位。美俄等军事大国大力发展的深钻地（核）武器已经对我国重要防护工程的生存造成了严重的威胁。本文总结了外军现役钻地（核）武器的性能指标与发展前景，对钻地武器的毁伤效应进行了评估和分析，综述了侵彻效应、爆炸成坑效应、爆炸地冲击效应等方面的研究成果。针对新时期的主要威胁，简述了提高防护工程防护能力的主要措施和技术途径，提出了主被动结合的综合防护体系、深部非线性岩体力学、摆型波与超低摩擦现象、多弹聚集打击效应等目前亟需开展研究的关键科学问题。

The protective engineering is an important constituent part of the deterrent force of national defense, and of great strategic position. The earth penetrating weapons (nuclear and non-nuclear) developing by countries with military power have already posed a great threat to the safety of our protective engineering. On the summary of the developing earth penetrating weapons, the damage effects of earth penetrating weapons are reviewed, with emphasis on penetrating effect, crater effect and explosion ground shock effect. Aiming at the main threatens, the major measures and technological approaches are discussed. And several key scientific problems, including comprehensive protection system, nonlinear deep rock mass mechanics, pendulum type wave and ultra-low friction phenomenon, and gather effect of several n-bombs, are proposed, which are with urgent need to be researched.
