13)TRANSPORTATION & HIGHWAY ENGINEERING
先把这科分为三个part,transportation,traffic和highway。
第一,我们先要知道transportation的意义。
traffic volume studies-是要学会算flow of traffic。
traffic safety-要将accident的数量减到最低。
road可以分为两种。rural和urban。
然后我们要知道road的结构。
pavement design--wearing course,binder course,base,subbase和subgrade。
还有很多关于公路上的司机,行人,地方环境,马路的状况,交通工具和交通数量的等等东西要知道,这都是theory part的东西多。
第二,重要的东西是intersection design,就是马路和马路之间的交叉点。有很多各式各样的intersections要学,就例如:T字路口,十字路口等等的。就当这些的intersections的tracffic volume增加时,未免会带来traffic和accident等等麻烦,所以我们会依照traffic volume的数量来design roundabout,traffic signal(交通灯)和其它的方法来解决这些问题。
第三,我们要学的东西是geometri design。当一座高速公路要开始动工时,我们就要design适当的slope,用适当的vertical curve和horizontal curve,以免太弯的路或太斜的路会带来不必要的accidents,也不会挡住远方的视线。
Transportation engineering: transportation systems, transportation planning, modes of transportation, transportation organizations, and transportation management. Traffic engineering: characteristics of the driver, pedestrian, vehicle and road; traffic engineering studies, intersection design and control, level of service. Highway Engineering: geometric standard design, pavement and drainage design |

14)HYDROLOGY & HYDRAULIC ENGINEERING
这科也分为两个part来教,hydraulic和hydrology。
我先讲hydraulic先,hydraulic大概是当水遇到压力时,会产生怎样的flow。这是比较的深入了解fluid mechanics的科目。先讲hydraulic,可以分为steady/unsteady flow,uniform/varied flow。而varied flow可分为rapid flow和gradually flow。我们要学地是算出那个flow的average velocity(using manning equation)和其它的calculations。过后我们要知道什么是rapidly varied flow。在这情况下会产生hydraulic drop和hydraulic jump。最后是要明白什么是gradually varied flow。通常纸上谈兵是不够的,在lab进行experiments可以令我们更深入了解。
hydraulic jump
hydrology里,我们要先明白hydrologic cycle的过程,那就是从下雨到变回云的过程。在开始时,我们要会一些的term的意思,就例如:runoff,streamflow,overland flow,catchment等等的字眼,这些都很重要。过后我们就要学算雨量的多少。要知道怎样从catchment(陆地)到drainage等等的东西。每个地区都有不同的雨量,我们可以根据manual saliran mesra alam malaysia(MASMA)来找出每年的雨量,用在equation里,就可以算出总共的雨量来design drainage之内的东西,以免产生水灾。
manual saliran mesra alam malaysia可是一系列的hydrology设计manual,在大马每一位工程师都要依照masma来design drainage的。
Hydraulic: Open channel flow basic principles: classifications, channel properties, energy and momentum principles, critical flow computations and applications. Uniform flow: development and formulas, computation of uniform flow, Gradually varied flow: theory and analysis, methods of computation, spatially varied flow. Rapid varied flow: flow over spillways, hydraulic jump.
Hydrology: hydrologic cycle, precipitation, infiltration, evaporation and transportation, steamflow, hydrologic measurement and monitoring, runoff and catchment, hydrographs, unit hydrograph, groundwater hydrology, rainfall - runoff relationship, river flow |

15)SOIL MECHANICS II
这科主要是更深入明白soil的一切。首先,我们要知道的是soil在面对pressure和forces(loading)时,会产生的变化,例如:soil的n meter下面会承受多少stress,整个foundation会下沉多少mm(settlement)。过后我们就要学backfill(soil)在一个retaining wall后面的pressure有多少。retaining wall可以分为几种,gravity wall,cantilevel wall等等。接着我们就要明白consolidation的theory。简单来讲是soil通常是有水份的(saturated clay),我们用适当的loading来将水份排除,以免saturated soil会比较容易下沉(settle)。我们会用很多的experiments来算不同的pressure可以排出多少的水份和settle多少。最后我们就要学会stability of slopes。通常在一个斜坡(slope)的部分,soil会比较松,所以我们要知道它们的承受量有多少(factor of safety)。

16)FOUNDATION ENGINEERING
foundation(地基)就是当我们要建一座建筑物时,最低层的,也是最先要建的部分。也是最重要的一部分,它的功能是将整个建筑物的loading放上在soil。这也要确保soil的稳定性,不然就会令整个建筑物倒塌。foundation有几种,spread foundation,mat foundation,pile foundation,drilled shaft foundation。
pile和drilled shaft foundation通常是用在大型的建筑物上的。首先,我们先要学的东西是bearing capacity,就是foundation压下去soil后,soil的承受量。要学会算ultimate bearing capacity和settlement。不同的soil有不同的formulas的,分别是clay和sand。当有load和moment压下时,我们也要会不同的formulas。过后我们就要学的是retaining wall的extenal stability。比较平常的是cantilevel wall。我们要check它的overtuning,sliding和bearing capacity failure。接下来我们要学的是braced cuts,那就是像H字形的,打两支sheet piles在旁边,中间就放struct bars来support。我们要会的是算旁边的soil的pressure。过后我们就要知道piles是什么。piles是concrete和steel制成的,要知道什么时候要用pile foundation,piles的种类和它们的功能。要学算piles的capacity和settlement。piles driving是把piles用drop hammer或steam hammer来打进地下。我们要算它们的allowable load可以到多少,以免将piles打烂。我们也要学会算group piles的bearing capacity和settlement。最后的drilled shaft foundations。也是有分好几种,straight shaft,bell shaft等等。我们也是要学算bearing capacity和settlement。
spread footing
mat footing
retaining walls
sheet piles
group piles
drilled shaft

17)STRUCTURAL ANALYSIS II
这科是structural analysis的part 2。要明白如何算因为整个科目都是用来算的。在这科,我们会用displacement method来analyzing structure。这个method有两种,slope-deflection equation和moment distribution。我们要analyze的structures有三种,beam,no sidesway frames和sidesway frames。要找的是moment。过后我们要学会用stiffness method来analyze trusses,beams和plane frames。最后我们要知道finite element method来analyze structures。

18)REINFORCED CONCRETE DESIGN I
这科可是在civil engineering扮演着重要的角色。首先,我们要知道reinforced concrete是什么来的,当我们在建一座建筑物时,我们一定会用到concrete的,不过在concrete里,我们就会放reinforcement(铁子)进去,这就是reinforced concrete。放reinforcement的原因是因为concrete只能承受compression force,不能承受tension force,当一条beam deflect时,它的下方就被拉的感觉,那就是tensile stress,所以我们就利用reinforcement放在concrete的下方来顶住tension force。简单来讲,我们是需要design几项东西,那就是beams,slabs,columns,walls,bases and foundations。我们是根据code book-BS 8110来design的,过后我们就要画出所有的layout,叫detailing。在这科里,我们会学到怎样design simply supported beam,continuous beam,short column和1-way slabs。还有我们要学会怎样checking,当我们design完毕时,我们要算出checking,是否可不可以达到它要的requirement。

还好啦。。。现在在consulting firm里工作。。。
至于教书,我是没兴趣的啦,可能我不是教书的材料。。。
楼主,你比我的lecturer厉害十倍,不。。。你简直是神。。。
我的lecturer什么都没教,每天上课只叫我们explore yourself...那还要lecturer来干吗。。。。 |

我也有遇见一些差的lecturers,也是要自己自修的。。。
所以自修也不是很悲观的事来的。。。
你可能会学到更多的东西的。。。 |

我知道,自修可能会学到更多的东西的。。。酱的话是可以学额外的东西,可是,考试成绩会不好噢。。虽然说成绩不是一切。。
你有什么书介绍?关于structure,steel or concrete?
可以让初学者明白的? |

请问malaysia的asphalt mix design多数是用marshall method还是superpave method
有什么不同?
这方面你熟悉吗?
你的大学有教吗? |

不怪得啦。。。我的大学完全没有进入detail。。。比如说。。。kajian tapak = soil mechanics 1 + 2....,reinforced concrete design = REINFORCED CONCRETE DESIGN I + REINFORCED CONCRETE DESIGN II ,pengenalan struktur = STRUCTURAL ANALYSIS II +STRUCTURAL ANALYSIS I,perhidmatan bangunan + teknologi infrastruktur = WATER & WASTEWATER ENGINEERING , asas ukur tanah = SURVEYING FOR ENGINEERS ,pengenlan pengurusan = PROJECT MANAGEMENT & CONSTRUCTION ....
忘了介绍。。。我是usm的,major building technology,看完版主的papers后。。。才觉得为什么讲的完全听不懂。。。因为实在太快了嘛。。。
一张paper要讲完两张paper的东西。。。唉。。。
不过我们还有学些sotfware....like 3d max,autocad....+ taking off, bill of quantities.....free hand sketching,drawing..... |
