Bearing Capacity of Soils

Bearing Capacity of Soils The bearing capacity of soils is perhaps the most important of all the topics in soil engineering. Soils behave in a complex manner when loaded so, it is important to know the bearing capacity of soils. Soil when stressed due to loading, tend to deform. ...

Subsurface Soundings

Subsurface Soundings The method of subsurface soundings consists of measuring the variation in the resistance offered by the soil with the depth by means of a tool known as penetrometer. The penetrometer may consist of a 50 mm diameter mild steel cone fitted loosely to a steel ro...

Probing

Probing In the probing method of site exploration, a steel bar of 25 to 40 mm. in diameter with a pointed end is driven in the ground until a hard sub-stratum is reached. The bar is driven by allowing it to fall vertically under its own self weight or by means of a drop hammer. [...

Test Pits – Soil Exploration

Test Pits The commonly used method to find the nature of the subsoil strata is to dig a hole and see. The holes which are large enough to permit the entry of persons for inspection are called ‘Test Pits’. The pits are normally square in plane and are dug by hand or by excavat...
