Abstract- Soil bearing capacity is an essential measure for construction purposes. Geogrid reinforced soil system is commonly used for improving properties. It helps in improving tensile strength. In this study, chopped carbon fiber(CCF) is used to improve the bearing capacity of the soil. These components create a reinforcing network within the soil, by increasing its internal friction and cohesion. This results in improving shear strength and bearing capacity. Carbon fiber is stronger than other geogrids like steel fibers. 0.5, 1,1.5, 2, 2.5, 3% of carbon fiber is initially used. Through direct shear test optimum measure of shear strength is calculated. Then bearing capacity calculation is done with optimum shear strength of carbon fiber along with welded wire mesh (WWM) on plate load. KeyWords: Bearing capacity, Plate load test, direct shear test, CCF, WWM.

INTRODUCTION
Bearing capacity is one of the most important factors that we consider while construction of a building. In old times bearing capacity is not calculated for the construction of the building. But in modern Times building Constructions done in weakest soil also. New methods of stabilization on the soil are adopted for the construction. Pile foundations are also used to transfer load from the building at the greater death on soil in the case of weakest soil. Basically there are many tests for calculating bearing capacity including plate load test. Basically carbon fiber is a fiber which is stronger than Steel fibers. Powder Carbon fiber is used for analysis. Soil is taken from mannanthala region. Along with the soil carbon fiber welded wire mesh is placed for the analysis. Bearing capacity of soil varies according to the soil type like silt, sand, clay and also varies due to material properties. Plate load tests are basically used for finding bearing capacity and settlement analysis. Dial gauge reading is measured in plate load test. Polyacryloriniye process is mainly used for majority of carbon fiber preparation. Cohesion and angle of internal friction can easily obtained from direct shear test.

Cui H et.al (2018) studied on effect of carbon fiber and nano silica on shear properties of silty soil and the mechanisms. The materials used are silty soil, carbon fiber and nano silica. 1%, 2%, 3% of carbon content and 1%, 2%, 3% of nano silica was used. Direct shear test was used for the analysis. Test is conducted for each percentage of carbon fiber and nano silica separately. Maximum shear strength obtained at carbon fiber of 2%, with carbon fiber only used. Maximum shear strength obtained at nano silica of 3%, with nano silica only used. Cohesion of sample with 2% carbon fiber and 3% of nano silica shows an increase of 15%. Akbar A et.al (2021) studied on plate load tests for investigation of the load settlement behavior of shallow foundation on bitumen coated geogrid reinforced soil bed. Soft soil and geosynthetics used for the analysis. Different grades of geogrids, width of reinforcement (1.5B and 4.5B), number of reinforcing layers and varying end conditions are used for the analysis. 1m x 1m x 1m steel tank is used. While increasing layer of geogrids, vertical displacement is increased. Plate load test is used for the analysis. It is founded that bearing capacity of geogrid reinforced clay increased. Looped layout is more effective and optimum width is4.5B for the analysis. Settlement reduction factor also increased. Consoli N.C et. al (2003) studied on the topic plate load test on fiber reinforced soil . Confining pressure, fiber is varied for the test. Plate load test, triaxial test are used for the analysis. From the observations Axial strain is larger than 20% from the initial case. Poly propylene fiber influence friction angle. Friction angle of compacted sandy soil and compacted fiber reinforced sandy soil are 30° and 31°.Cohesion intercept at failure of compacted sandy soil and compacted fiber reinforced sandy soil are 23KN/m² and 127 KN/m².Addition of polypropylene fiber improves strength of soil. Bao X. et .al (2021) studied on the topic experimental investigation on mechanical properties of clay soil
