Abstract

The population pressure on most of our major cities compels us and provides really an unique opportunity to bring about a new urban environment using the enormous growth of the next 25 years to completely reconstruct the urban pattern which accidents of history have created for us to live in today. Survival of our cities depends largely upon how they would be able to serve the needs functionally. Cities are bound to grow, for growth is the law of life and the best cities tend to over-grow through the energy of their populations and the satisfactions people get from their environment.

Structural loads compressing the underlying soil, tend to deform the soil structure by relatively displacing the soil particles from their original position, or bringing the soil particles closer together, resulting in decrease in the volume of the soil. In case of clayey saturated soil, the change in volume is attributed mainly to the expulsion of water out of the voids of the coheive soil.

There is no doubt that the provision of modern road system in a country is an essential pre-requisite of industrial recovery.

Unless it is built on solid hard rock, every structure will have to be founded on soil and the choice of an adequate foundation is one of the first problems to be seriously considered in any constructional project.
