Concept explainers

Calculation of Settlement

The vertical displacement of the structural foundation due to the loading from the superstructure is known as settlement. It is due to the reduction of air voids present in the soil. The amount of vertical displacement depends on the bearing capacity of the soil on which the foundation is laid. The effect of the settlement depends on the magnitude of settlement, uniformity, and the structural design of the structure. The maximum allowable settlement for residential and office buildings should be less than 18 mm, for industrial buildings, it is 38 mm and for commercial buildings, it is 25 mm.

4) In a oedometer test a specimen of a saturated clay 21 mm thíck reaches 50% consolidation in 10 minutes. How long would it take a layer of this clay 6 m thíck under the same drainage conditions to reach 90% f consolidation under the same stress and drainage conditions? Use the following relationships between the average degree of consolidation, U and time factor, T,: U =T, for Us 50% U =1-- for U>50% No need for calculation, please write only the results.
