DESIGN & ANALYSIS OF ‘MOHMAND DAM’

Abstract

Mohmand Dam Project is an ongoing project in Pakistan. It’s a CFRD (Concrete Faced Rockfill Dam) being built in response to the flooding conditions in the area. This study deals with the design and construction aspects of the dam. This includes carrying out all the necessary calculations needed for the designing of its embankment such as the hydrological study and dam sectioning. The procedures generally employed for checking the stability are the limit equilibrium methods and this study will delve further into it as well as the finite element modelling of the dam which is done by use of software such as PLAXIS, ABAQUS and SLIDE 2D is done to check the dam body i.e. embankment safety. The cost of its embankment is also drawn with respect to its height while ensuring the best material provision. The study aims to provide the general guidelines for establishing the embankment of a Concrete Faced Rockfill dam, its zoning and checking its stability against seepage as well as earthquakes. This results in an optimal and sophisticated design which will bear all the undesired conditions as well as providing a range of different heights of dam to be used in accordance with the economic conditions.
