12、ture rarely duplicates another exactly.土木工程学科特别具有挑战性，这是由于工程师设计和建造的每一幢建筑物或每一个系统几乎都是独一无二的，一种结构几乎不可能与另一种结构完全相同。,Even when structures seem to be identical,site requirement or other factors generally result in modification.Large structures like dams,bridges,or tunnels may differ substantially from previo
13、us structures.,Even when structures seem to be identical,site requirement or other factors generally result in modification.Large structures like dams,bridges,or tunnels may differ substantially from previous structures.即便外表看上去相同的建筑物，由于场地要求或其他因素的改变通常会导致设计方案的不同。大型建筑物如堤坝、桥梁或隧道工程，可能与以前的结构有实质差异。,Enginee

15、 must also adapt themselves to two requirements of all engineering projects.工程师必须愿意接受继续教育并且能够在其他领域工作。他们必须具有工程技术所要求的两个必要条件。,First,the system that engineers produce must be workable not only from a technical but also from an economic point of view.This means that engineers must cooperate with manageme
16、nt and government officials who are very cost-conscious.,First,the system that engineers produce must be workable not only from a technical but also from an economic point of view.This means that engineers must cooperate with management and government officials who are very cost-conscious.其一是工程师所提出的
17、措施必须在技术和经济方面均可行，这意味着他们要与关注经济成本的管理人员和政府官员合作。,Second,the public in general has become much more aware of the social and environmental consequences of engineering project,and of the hidden or delayed hazards in new products,processes,and many other aspects of civil engineering system.,Second,the public
18、 in general has become much more aware of the social and environmental consequences of engineering project,and of the hidden or delayed hazards in new products,processes,and many other aspects of civil engineering system.其二，公众通常更关心工程产品对社会和环境产生的影响，以及新产品、建设过程本身和许多其他在土木工程系统中所隐含的或后显的危害性。,Engineers are r
