Question 5An earth dam is proposed for a site consisting of a homogeneous stiff clay, as shown in the Fig. below. You, the geotechnical engineer, are required to specify soil strength tests to determine the stability of the dam. One of the critical situations is the possible failure of the dam by a rotational slip plane in the stiff clay. What laboratory strength tests would you specify and why?Question 5 An earth dam is proposed for a site consisting of a homogeneous stiff clay, as shown in the Fig. below.

You are the geotechnical engineer for a proposed office building in a densely clustered city. The office building will be constructed adjacent to an existing office complex. The soil at the site is a deposit of very dense sand with E = E’= 45 MPa and v = v’ = 0.3. The sand rests on a deep deposit of dense gravel. The existing high-rise complex is founded on a concrete slab, 100 m 3 120 m, located at 2 m below ground surface, and transmits a load of 2400 MN to the soil. Your office foundation is 50m x  80m and transmits a load of 1000 MN. You also intend to locate your foundation at 2m below ground level. The front of your building is aligned with the existing offi ce complex, and the side distance is 0.5 m. The lesser dimension of each building is the frontal dimension. The owners of the existing building are concerned about possible settlement of their building due to your building. You are invited to a meeting with your client, the owners of the existing building, and their technical…
