The excavation for a caisson to carry a total load of 1500 kN is to be drilled dry in the soil profile shown in Fig. 11-8. The caisson will be made of concrete with f: of 27,500 kN/m2. It is specified that the unit compressive stress of the caisson shaft shall not exceed 33% of its ultimate 28-day compressive strength nor 8274 kN/m2. Find the required diameter of the plain concrete straight-shaft caisson.
