(a) 1/√G – K
(b) 1/ (G – K)u
(c) 1
(d) 1/√ (G2 – K2)
The ratio of base width ‘b’ to height ‘h’ of an elementary profile of a gravity dam from ‘no tension’ consideration is given by 1/√G – K. Check the detailed explanation related to the ratio of base width to height of a gravity dam from ‘no tension’ consideration below.
Ratio of Base Width to Height of a Gravity Dam from ‘No Tension’ Consideration
Elementary Profile of Dam: A gravity dam’s theoretical cross-section has a basic profile when it is simply being affected by the three principal forces of self-weight, water pressure, and uplift pressure. Additionally, the elementary profile has no freeboard and zero top width.
Base width for no tension at the heel is given by b/H=1/√ (G-K)
Where,
- G=specific gravity of the material
- H=height of the water level at an upstream end
- K = coefficient of uplift pressure
Summary:
The ratio of base width ‘b’ to height ‘h’ of an elementary profile of a gravity dam from ‘no tension’ consideration is given by Where G = specific gravity of dam material K = uplift pressure intensity μ = coefficient of friction (a) 1/√G – K (b) 1/ (G – K)u (c) 1 (d) 1/√ (G2 – K2)
1/√G – K is the ratio of base width to height of an elementary profile of a gravity dam from ‘no tension’ consideration. The explanation for the same has been illustrated in this page above.
