Methods of Improving the Bearing Capacity of soils

Content of the article : methods of improving the bearing capacity of soils  Methods of Improving the Bearing Capacity of soils The bearing capacity of a soil mainly depends on the closeness of its particles. The bearing capacity of a soil can be increased by the following methods: By increasing the depth of foundation. The compactness of the foil increases as we go below the ground level. As the bearing capacity directly depends on the compactness of the soil, it will go on increasing as the depth of foundation is increased. By draining of the sub-soil under.  Water reduces the cohe­sive properties and hence reduces the bearing capacity of the soil. By draining off water from the sub-soil the bearing capacity of the soil is certainly increased. By compacting the soil.  If the soil is compacted thoroughly, the voids are decreased and bearing capacity is increased. By confining the soil…

Soils and their Bearing Capacity

Content of this article : Bearing capacity of soils,Methods of determining the Bearing Capacity of Soils,Safe Bearing Capacity.factor of safety,safe bearing capacity of different soils. Soils and their Bearing Capacity The soils on which a structure rests may be classified into three categories: (a) Hard soils. These soils are generally rocky in nature, in compressible and can bear fairly good loads. Solid rock, moo rum and stony soils are examples. (b) Soft soils. These are alluvial soils and are compressible when loaded. They can to take much load. Ordinary clay, loam, and common soils are examples of this. (c) Spreading soils. These soils are compressible when they are confined and prevented from spreading. These soils when load­ed spread out laterally. Sand and gravel are examples of this type of soil. Bearing capacity of soils. Bearing power or Bearing capa­city of a soil is defined as the maximum load that a…

The loads coming on the foundations

Loads The loads coming on the foundations are generally divided into (i) Live Load (ii) Dead Load (iii) Wind Load and (iv) Snow load. (i) Live Load: It is a temporary or moving load. The weight of the inhabitants of a building, the weight of furniture or any stored material is called Live Load. Sometimes the live load is also called super-imposed load. For designing foundations, the live load on the structure is also taken into account. (ii) Dead Load: It is the permanent load of the structure, i.e. the weight of the structure itself. The weight of the walls, floors, roofs, weight of fixed machinery and any immovable load, is called dead load. (iii) Wind load: When the wind blows, it causes a lateral thrust or pressure on the vertical as wall as the inclined embers of the structure. This wind pressure is called wind load. The ten decay…
