Here is this post I will not be discussing about the whole subject of course because it is out of the scope of the post, below are simple, useful and important questions along with answers which all geo-tech and civil engineers must know Why foundation is necessary? Well a common question but very simple answer could be, how will you stand if you don’t have feet? Obviously you will not be able to stand on your own load, thus to stand the loads of the building along with the live load of persons, machinery etc, footing is needed secondly if we place the column or wall directly over the footing the wall or column will sink easily due to high contact pressure.Ĭontact pressure is decreased by increasing surface area and this is where the footing plays its role to distribute the load over a larger or wider area. Geo-technical and foundation engineering MCQS The ultimate destiny of any load in the structure is the underneath supporting soil and the mean which we adopt for this transfer is footing. The portion upon which the load of building or super-structure rests is called a foundation and the lower part of the foundation is footing. Like the name of the subject it plays a pivotal role in the success or failure of any structure.
Foundation and geo-technical engineering is a very interesting and useful field of civil engineering.
