T
10、he relationship between engineering and society is getting closer; it is sufficient, therefore， to say again that the work performed by an engineer affects society in many different and important ways that he or she should be aware of。 An engineer also needs a sufficient command of language to be ab

Many different corporation and government agencies have competed for the services of engineers in recent years。 In the scienceoriented society of today, people who have technical traini

Indeed， the choice is large and varied.近年来，许多不同的公 司和政府机构为争夺工程师而竞争。在今天 这个重视科学技术的社会，受过技术训练的 人当然是受欢迎的。年轻工程师也许选择进 入环境或卫生工程领域工作， 例如， 在环境问 题方面创造的许多机会; 或他们也许选择专门 的高速公路工程的建筑公司； 或他们也许喜欢 与政府机构当中处理水资源的机构之一共事。 的确, 选择很多且多样。 When the young engineer has finally started act

22、g projects are almost always unique; that is, each has its own problems and design feature. Therefore， careful study is given to each project even before design work begins. The study includes survey both of topography and subsoil features of the proposed site. It also includes a consideration of po

25、 土木工程项目几乎是唯一(独一）的； 就是 说，每个工程有它自己的难题和设计特点。 所以, 在设计工作开始以前，要仔细的研究每 个项目。研究包括勘测工程位置的地形和地 基特点。它还包括考虑可能的比选方案， 譬如 一个混凝土重力式坝或填土的土石坝。经济 因素与在每个可能的比选方案有关，也必须 斟酌。今天， 研究通常包括项目的环境影响的 考虑.许多工程师， 通常在一起工作组成一个 团队，这个团队包括测量员、土力学方面的 专家和设计施工方面的专家,来参与制定这 些可行性研究. Many civil engineers， among them the top people in the field,
26、work in design. As we have seen, civil engineers work on many different kinds of structures, so it is normal practice for an engineer to specialize in just one kind。 In designing buildings, engineers often work as consultants to architectural or construction firms。 Dams， bridges, water supply system

In many cases, engineers from other disciplines are involved. In a dam project， for example， electrical and mechanical engineers work on the design o

30、总工程师） ，他们的工作是协助负责整个 项目。在许多情况下， 也需要（涉及）其它学科的 工程师。例如,在水坝项目中, 电子和机械工程师负 责发电站及其设备的设计。在其它情况下, 土木工 程师被分配到其它领域的项目上工作； 例如,在空间 项目中, 需要土木工程师设计和施工诸如发射台和 火箭存贮设施这样的结构。Construction is a complicated process on almost all engineering projects。 It involves scheduling the work and utilizing the equipment and the mate
31、rials so that costs are kept as low as possible. Safety factors must also be taken into account， since construction can be very dangerous. Many civil engineers therefore specialize in the construction phase. Scheduling n 行程安排， 进度安排 utilize 利 用，使用 take into account 考虑，重视 civil engineer n.土木工程师 specia

33、 are the Pantheon and the Colosseum in Rome, Hagia Sophia in Istanbul; the Gothic churches of France and England， and the Renaissance cathedrals， with their great domes, like the Duomo in Florence and St. Peters in Rome。 They are massive structures with thick stone walls that counteract the thrust o

36、uct of knowledge of mathematics and physics。 They were constructed instead on the basis of experience and observation, often as the result of trial and error。 One of the reasons they have survived is because of the great strength that was built into themstrength greater than necessary in most cases.
37、 But the engineers of earlier times also had their failure. In Rome， for example, most of the people lived in insulae, great tenement blocks that were often ten stories high. Many of them were poorly constructed and sometimes collapsed with considerable loss or life. 第二段 生词 instead adv。 不是。而是，代替,当作,
38、 trial and error n.反复试验,不断摸索 insulae 公寓，群屋 tenement block n。 经济公寓 poorly adv。 拙 劣地，贫乏地 considerable adj.相当大(或多）的 collapse n。倒塌，崩塌 这些伟大的建筑不是数学和物理知识的产 物。而是根据经验和观察建造的， 经常是不断 摸索的产物.他们依然存在的原因之一是由 于被修建得能承受很大的力量-在许多情况 下大于他们需要的力量。但更早的时期的工 程师也有过失败。例如，在罗马, 大多数人民 , ， 居住在公寓里， 大的经济公寓经常有十层楼高。 许多修建得很拙劣且不时倒塌,造成了了相
39、当大的财产或生命损失。 Today， however， the engineer has the advantage not only of empirical information， but also of scientific data that permit him to make careful calculations in advance. When a modem engineer plans a structure, he takes into account the total weight of all its component materials。 This is k
40、nown as the dead load, which is the weight of the structure itself， He must also consider the live load， the weight of all the people， cars, furniture, machines, and so on that the structure will support when it is in use。 In structures such as bridges that will handle fast automobile traffic， he mu
41、st consider the impact, the force at which the live load will be exerted on the structure, He must also determine the safety factor, that is, an additional capability to make the structure stronger than the combination of the three other factors. empirical adj.完全根据经验的， 经验主义的 in advance 提前；预先 plan vt

43、， 机器, 等等 结构在使用中需要承受的荷载。结构，比如 桥梁将要承受高速的汽车通行(行使)，它 必须考虑冲力力，这个力是活载作用在结构 上的.他还必须确定安全因素,也即是,额 外的承载能力以确保结构的强度大于这三个 其他因素的组合作用。 The modern engineer must also understand the different stresses to which the materials in a structure are subject。 These include the forces of compression and tension。 In compressi
44、on the material is pressed or pushed together； in tension the material is pulled apart or stretched， like a rubber band. In addition to tension and compression, another force is at work, namely shear， which we defined as the tendency of a material to fracture along the lines of stress. The shear mig
45、ht occur in a vertical plane， but it also might run along the horizontal axis of the beam, the neutral plane， where there is neither tension nor compression. Subject使受到, 使遭到 compression 压力，压缩 tension拉力 Press 挤压,受压 pull apart v.撕开 stretch v.伸展， 伸长 rubber band n。橡皮圈 at work adv.在工作， 在运转,在起作用 shear 剪力
46、fracture v.（使)破碎， （使）破裂，断裂 vertical plane n。垂直面 horizontal axis水平轴 neutral plane中性面 现代工程师还要知道结构中材料承受的不 同的力。这些力包括压力和拉力这对互反的 力.受压时，材料受到挤压或是被推倒一起; 受拉时，材料被撕开或是被拉长，就像一根 橡皮圈。除了拉力和压力以外，还有另一种 力作用于结构上，也就是剪力,我们定义使 材料趋于沿着力的作用线断裂的力为剪力。 剪力可能在垂直面作用，但是也有可能沿着 梁的水平轴，既不受拉也不受压的中性轴作 用。 Altogether, three forces can act
47、on a structure： vertical-those that act up or down; horizontalthose that act sideways； and those that act upon it with a rotating or turning motion. Forces that act at an angle are a combination of horizontal and vertical forces。 Since the structures designed by civil engineers are intended to be st
48、ationary or stable， these forces must be kept in balance. The vertical forces， for example, must be equal to each other。 If a beam supports a load above, the beam itself must have sufficient strength to counterbalance that weight. The horizontal forces must also equal each other so that there is not
49、 too much thrust either to the right or to the left。 And forces that might pull the structure around must be countered with forces that pull in the opposite direction。 act on v。对.。起作用，作用于 act 产生.。的效果,担当，见效 vertical 垂直的 horizontal 水平的 sideways adv.向一旁 rotating转动的， 旋转的 turning n。旋转, 转向 motion n。运动， 动作 stationary固定的 stable adj。稳定的 counterbalance vt使平衡 thrust 推力 opposite direction相反方向，反向 总之，这三个力会作用在结构上：竖直的-那些向上或向下作用的力；水平的那些向 一侧作用的力；以及那些使旋转或转动的作 用力。以一个角度作用的力是水平力和竖向 力的合力。因为由土木工程师设计的结构要
