Deflection Due to Thrust Calculator

Posted by Dinesh on

Use this simple rock movements calculation tool helps to compute the deflection due to thrust for your hydraulics and waterworks problems. If the ends of the arch elements are vertical, and the bases of the cantilever elements, horizontal, rock rotations and deflections of elements with parallel sides 1 ft apart may be calculated by the formula: ?' = (H * K2) / (Er).

Values of K Constants in Eqs. (12.193) to (12.198) for Poissons Ratio = 0.20

Deflection Due to Thrust - Rock Movements Calculation

Formula:

?' = (H × K2) / (Er)

where,
  • H - Arch thrust
  • K2 - Poissons ratio constant
  • Er - Elastic modulus of the rock
  • ?' - Deflection due to thrust
