THE BOOK
This book provides a comprehensive description of the analysis and design process of some hydraulic concrete structures designed to retain and contain aqueous liquid. The first edition discussed six types of structures of different functions, namely:
(a) An underground sedimentation tank for sewage treatment.
(b) An underground digestion tank for sludge treatment.
(c) An underground reservoir to store fresh potable water.
(d) An immersed highway tunnel under the river bed.
(e) An indoor swimming pool of rectangular shape for public
recreation.
(f) A gravity dam across a valley for converting the valley into a
fresh water reservoir.
This Second Edition incorporates another type of hydraulic structure, namely spillway.
The spillway structure plays a vital role in regulating the designed reservoir water level to meet the fluctuating demand of water supply for the generation of hydroelectricity, irrigation and water supply purposes in controlling the height of reservoir water level downstream of the river. The spillway structure subjected to seismic hydrodynamic pressure in addition to the hydrostatic pressure, has been analysed and designed in full compliance with Eurocodes EC 2: Part 1–1 and Part 3 as water-retaining structure. The other six structures have been analysed and designed with reference to the relevant clauses of codes of practice prescribed in Eurocodes 2 and BS 8007 and BS 8110.
