释
natural disaster mechanics
环境灾害力学
研究自然灾害发生、发展、演化规律、机理及其影响的一门力学和地球科学交叉的力学学科。其中,自然灾害或环境灾害指的是人和生物周围的环境条件,如温、湿、风、气压、降水(雪)、大气组分、水位、水流、海浪、水质、坡体(地基)稳定性等大幅度急剧变化,从而危及人类的生命和财产安全的极端事件,也称为自然灾害。它区别于诸如:瓦斯突出、工程塌方、粉尘爆炸、火灾燃烧、化学品泄漏等导致的工业(程)灾害,除了核爆炸或核泄露外,一般说来环境(自然)灾害的影响程度更严重,范围更广。由于环境灾害发生的原因是由异常的自然现象引起,与自然界的物质和能量输运有关,所以,它也是环境力学的重要组成部分。
