Question

Определите давление,которое производит бетонная стена высотой 15м на фундамент? Плотность бетона 2200кг/м3

Answer 1

2200 х 15 = 33000 кгс/м2

Answer 2

Calculation of Pressure Exerted by a Concrete Wall

To calculate the pressure exerted by a concrete wall on its foundation, we need to consider the height of the wall and the density of the concrete.

Given: - Height of the concrete wall: 15 m - Density of concrete: 2200 kg/m³

Formula for Pressure

The pressure exerted by a column of fluid (in this case, the concrete wall) is given by the formula:

Pressure = Density × Gravity × Height

Where: - Density is the density of the fluid (in this case, the density of concrete) - Gravity is the acceleration due to gravity (approximately 9.8 m/s²) - Height is the height of the fluid column (in this case, the height of the concrete wall)

Calculation

Let's calculate the pressure exerted by the concrete wall on its foundation.

Density of concrete = 2200 kg/m³ Height of concrete wall = 15 m

Using the formula for pressure, we can substitute the given values:

Pressure = 2200 kg/m³ × 9.8 m/s² × 15 m

Calculating the above expression, we get:

Pressure = 323,400 Pa

Therefore, the pressure exerted by the concrete wall on its foundation is approximately 323,400 Pascal (Pa).

Please note that this calculation assumes a uniform distribution of the weight of the concrete wall on its foundation. In reality, the pressure distribution may vary depending on the design and construction of the wall and foundation.
