CIVL 0014 Railway Engineering - Middle East College

Learning Outcome 1: Employ methods of analysis for railway economics.

Learning Outcome 2: Calculate and tabulate data for plain line design.

Learning Outcome 3: Apply industry standards in gauging and clearances design, including use of software, and demonstrate understanding of situations in which standards are not appropriate.

TASK 1

Railway transportation became a more vital need for society, the need to increase the speed of trains became more and more important. This lead to many improvements in railway practices and engineering. Design speed is the principal factor controlling horizontal alignment design. When a train rounds a curve, it has a tendency to want to travel in a straight direction and the track must resist this movement, and force the train to turn. Suppose a 400 m radius curve is introduced between straight portions of a Meter
Gauge Railway line intersecting to form a total deviation of 80 degrees. The speed for determining the equilibrium cant is fixed at 90 km/h and the maximum sectional speed is 120 km/h.
• Calculate the equilibrium cant,
• The maximum permissible speed, and
• Length of transition.
Can't deficiency are 165 mm and 100 mm. respectively.

TASK 2
An appraisal of five alternatives, mutually exclusive projects in different cities in Oman, is being made for a company that requires a benefits of at least 5 % on its invested capital. Which of these projects is best?

The estimated details of the investment are shown in the table below. Consider alternative projects, either of which would cost 70,000 OMR today and yield benefits over a four -year period as follows:

Year	1	2	3	4
Muscat Project	60,000 OMR	30,000 OMR	16,000 OMR	19,000 OMR
Nizwa Project	20,000 OMR	40,000 OMR	19,000 OMR	32,000 OMR
Sohar Project	42,000 OMR	16,000 OMR	24,000 OMR	20,000 OMR
Rustaq Project	33,000 OMR	22,000 OMR	12,000 OMR	27,000 OMR
Salalah Project	38,000 OMR	23,000 OMR	29,000 OMR	25,000 0MR

(Example: you were born 24/9/1977, it must be found the static wheel load 1977 KN and the wheel load carries 24 %)

TASK 3

By using Indian railway dynamic formula, when velocity are 100 km/h and 150 Km/h, according to the data given. Find the stress in each layer contact as below

1. Determine the maximum stress when running speed is 100 km/h.
2. Demonstrate mathematically reduction stress ratio between rail contact pressure and ballast pressure under sleeper in the event that speed 150 km/h.
3. Evaluation increased percentage of sleeper/ ballast contact pressure when train is speeded up from 100 to 150 km/h

CIVL 0016 - Geotechnology

Learning Outcome 1: Analyse the stability of retaining structures; how to predict the performance of piled foundations; how to analyse the stability of slopes (including rock slopes); the application of the concept of seepage in permeable ground, the philosophy of Dam Engineering; and the basic concept of critical state soil mechanics

OBJECTIVES
i. To carry out the analysis and design of geotechnical structures specified in the assessment brief with considerable emphasis on sustainability and safety requirements
ii. To interpret the design outputs
iii. To prepare and submit a technical report that follows a standard report protocol

Q1:
a) Supported by evidence in the literature, critically reflect on (i.e. in your own words) the circumstances under which pile foundations are necessitated - 200 words
b) After a thorough investigation of site conditions, it has been decided to provide design of a 3 x 4 pile group for a high-rise building in Muscat. Two sites were selected.
SITE A: a layered fine-grained soil consisting of loose clay underlain by stiff clay
SITE B: a layered coarse-grained soil consisting of loose sand underlain by gravely layer
(10 marks) Referring to your individual soil data, determine the ultimate structural load that can be allowed on the pile group and interpret your results.

Q2:
a) It is required to check the stability of a layered soil slope shown below using any two methods of slices. In order to ensure accuracy of the method, a minimum of five (5) slices should be considered for analysis. Note however that the more number of slices the more the accuracy improves. Individual soil data is provided in a separate file in Moodle.
b) Appraise the critical state soil mechanics concept. You may evaluate this concept in relation to the classical soil mechanics currently followed in geotechnics.
