土木工程与国家基本建设和人民生活戚戚相关,不仅需要国家的大量投资而且其后果往往要延续百年,对国家的现在与未来都有重大影响。值得注意的是土木工程中的大量问题并不是依靠计算解决的。例如,结构在遭受自然灾害袭击时的损失预测是难以直接计算的。重大工程项目的设计方案也往往不是由一个优化程序算出,这里常常需要专家们从多目标分析 Civil engineering is closely related to the nation’s capital construction and people’s livelihood. It requires not only massive investment from the state, but also its consequences, which often last for a hundred years, exerting a significant influence on the present and future of the country. It is noteworthy that a large number of civil engineering problems are not calculated by the solution. For example, predictions of loss of structure in the event of a natural disaster are difficult to calculate directly. Design projects of major projects are often not calculated by an optimization program, where often require experts from multi-objective analysis
