Why we made shallow foundation instead a deep foundation

Describe the types of deep foundations.

A square footing, 1.7 m x 1.7 m, is to be founded at a depth of 1.4 m below the ground surface of a deep clayey sand stratum. The saturated unit weight of the soil is 17 kN/m3. Based on drain triaxial tests, the soil parameters are c' = 7 kPa and ø' = 25°. The ground water table was found at the surface level. The foundation is to carry a permanent load of 280 kN and a variable load of 210 kN.

On what basis the Empirically developed foundation design method are based on?

You are assigned the foundation design of a 56'-0" inside diameter reinforced concrete process tank. Vertical walls are 1'-0" thick and 15 feet high, terminating at elevation 25.00. Bottom of wall is at elevation 10.00 and rests on the foundation slab. Exterior grade abutting the vertical tank walls is at elevation 22.00. The tank foundation slab is circular with a two foot extension all around the vertical tank exterior wall. Determine the minimum height of the foundational circular slab. For design purposes consider the groundwater to be saturated to sit grade. Determine the following: A) Buoyant force in pounds B) Minimum depth of foundation slab in feet

An engineer is responsible to design a safe and stable foundation that can transmit the loaduniformly under the structure. You are assigned to design a foundation for a double- storeyreinforced concrete shop house in Batu Pahat, Johor. FIGURE Q4(a) and FIGURE Q4(b) showthe layout plan and artist illustration for the building, respectively. The soil condition of theconstruction site is soft clay with a low bearing capacity value.  Briefly explain FIVE (5) factors that need to be considered in the design

Define the importance of a solid foundation.

)A tall rise building is to be built on soft saturated clay. Discuss the possible foundation types on that soil. Discuss and compare how the design process would be in case of sandy soil. Discuss possible issues that you might face on design process for both sandy and clayey soil.

True or false? For reinforced concrete footings, the size is calculated to satisfy the bending and shear strength of the concrete footing.
