๐Ÿ‘‰What Is Bearing Capacity Of Soil?

๐ŸšงThe maximum load per unit area which the soil can carry without any settlement or displacement is termed as bearing capacity of the soil.

๐ŸทBearing capacity of soil is determined by the following two methods:-

1. Dropping weight method.
2. Slowly applying load method.

๐Ÿ’ซUltimate Bearing Capacity Of Soil:

โบThe minimum load on unit area causing failure is called the ultimate bearing capacity of the soil.

๐ŸŒŸSafe Bearing Capacity Of Soil:

โบThe maximum intensity of loading that the soil will safely carry without the risk of shear failure is called safe bearing capacity of the soil.

โบIt is obtained by dividing the ultimate bearing capacity by a certain factor of safety which is used in the design of foundation.

โ–ถ๏ธThe value of factor of safety varies from 2 to 3 depending upon the nature of the soil.

โ‡๏ธMaximum Safe Bearing Capacity Of Different Types Of Soil:

1. Soft, wet clay or muddy clay โ€” 5,000 kg/m2
2. Soft clay  โ€” 10,000 kg/m2
3. Fine, loose and dry sand  โ€” 10,000 kg/m2
4. Black cotton soil  โ€” 15,000 kg/m2
5. Moist clay and sand clay Mixture โ€” 15,000 kg/m2
6. Loose gravel โ€” 25,000 kg/m2
7. Medium clay โ€” 25,000 kg/m2
8. Medium, compact and dry sand โ€” 25,000 kg/m2
9. Compact clay โ€” 45,000 kg/m2
10. Compact sand โ€” 45,000 kg/m2
11. Compact gravel โ€” 45,000 kg/m2
12. Soft rocks โ€” 45,000 kg/m2
13. Laminated rock such as sand stone &  Lime stone โ€” 165,000 kg/m2
14. Hard rocks such as granite, diorite, trapโ€“  330,000 kg/m2

๐Ÿ‘‰Waffle Slab

๐ŸšงWaffle slab is a reinforced concrete roof or floor containing square grids with deep sides and it is also called as grid slabs.

โ–ถ๏ธThis kind of slab is majorly used at the entrance of hotels, Malls, Restaurants for good pictorial view and to install artificial lighting.

โ–ถ๏ธThis a  type of slab where we find a hollow hole in the slab when the formwork is removed.  Firstly PVC trays (pods) are placed on shuttering then reinforcement is provided between the pods and steel mesh is provided at top of the pods and then concrete is filled. After concrete sets, the formwork is removed and PVC pods are not removed.

โ–ถ๏ธThis forms a hollow hole in it in which hole is closed at one end.

โ–ถ๏ธThe concrete waffle slab is often used for industrial and commercial buildings while wood and metal waffle slabs are used in many other construction sites.

โ–ถ๏ธThis is one of the types of concrete slabs.

๐Ÿ’ซWhere to use Waffle Slab & Waffle slab details:

โบA waffle slab has a holes underneath, giving an appearance of waffles.

โบIt is usually used where large spans are required (e.g auditorium, cinema halls) to avoid many columns interfering with space. Hence thick slabs spanning between wide beams (to avoid the beams protruding below for aesthetic reasons) are required.

โบThe main purpose of employing this technology is for its strong foundation characteristics of crack and sagging resistance.

โบWaffle slab also holds a greater amount of load compared with conventional concrete slabs.

๐Ÿ”ฐTypes of Waffle slabs:

โ–ถ๏ธBased on the shape of Pods (PVC Trays) waffle slabs are classified into the following types:

โนTriangular pod system and
Square pod system

๐ŸŽฒAdvantages of Waffle slabs:

โ‡๏ธWaffle slabs are able to carry heavier loads and span longer distances than flat slabs as these systems are light in weight.

โ‡๏ธWaffle slab can be used as both ceiling and floor slab.
Suitable for spans of 7m โ€“ 16m; longer spans may be possible with post-tensioning.

โ‡๏ธThese systems are light in weight and hence considerable saving is ensured in the framework as the light framework is required

๐ŸทDisadvantages of Waffle slabs:

โบWaffle slab is not used in typical construction projects.

โบThe casting forms or moulds required for precast units are very costly and hence only economical when large scale production of similar units are desired.

โบConstruction requires strict supervision and skilled labour.

๐Ÿ‘‰Water ponding on roads can cause damage due to several factors:

๐Ÿšง1. Hydrostatic Pressure

โบProlonged water accumulation increases pressure on the pavement, leading to cracks and structural weaknesses.

๐Ÿšง2. Erosion

โบWater can erode the sub-base and subgrade layers, weakening the pavement support.

๐Ÿšง3. Freeze-Thaw Cycles

โบIn colder climates, water can freeze and expand within cracks, causing further deterioration.

๐Ÿšง4. Material Degradation

โบWater can weaken materials like asphalt, leading to potholes and surface failures.

๐Ÿšง5. Loss of Adhesion

โบMoisture can strip the binding agents within asphalt, reducing durability.

๐Ÿ’ซPreventive measures include proper drainage design and regular maintenance to ensure water doesn't accumulate on road surfaces.

Dynamic cone penetration penetrometer

โžช Dynamic cone penetration
penetrometer or DCP is a tool used
for evaluating the strength of soil on site.
โžช It also helps with monitoring the condition of granular layers and sub
grade soils in pavement section over time.

โžช It can be the right choice for site
with soft soil

โžช it is also applied when the CBR value of compacted soil sub-grade beneath the existing road pavement is to be determined. Continuous reading can be taken down to depth of 800mm or when an extension rod is fitted to be a depth up to 1200 mm.

โžช The DCP is simple and portable
instrument. It consists of hardened conical tip, standard diameter steel
rod , and standard weight hammer (8kg) , which is dropped from the top of the rod against an anvil to advance the tip into the ground.

DCP test results are expressed in DPI.

DPI is defined as the amount of vertical movement of the DPC cone produced by one drop of hammer. Itโ€™s expressed in millimeters. Strong souls have lower DPI than weaker soil.

Next time we will show you how to calculate DPI value.
