If the sub soil conditions are not suitable for the required constructions then soil strata have to be modified as per requirements. The weak strata can be analysed from depth vs N value graph. From Atterberg's limit values LI is calculated, by substituting LI value undrained shear strength ...
The SPT (N-values) provides information about the resistance of soils to penetration, which can be used to assess various soil parameters (i.e. unit weights, internal angle of friction, cohesion, compaction etc). The major disadvantages of this method are that it requires mobilization of heavy...
ABSTRACT One of the field investigations to determine the characteristics of the soil is Standard Penetration Test (SPT). In the SPT test, soil samples can also be obtained, then it can be used to determine the physical and mechanical properties of a soil. Meanwhile, the value of SPT (N-...
