Web25 Apr 2024 · This study is an attempt to evaluate relative density and friction angle of sands on the basis of SPT-N values. In order to develop the relationships among relative density ( D r ), friction angle ( ϕ) and SPT-N value, field and laboratory test results from sixty boreholes executed in sandy deposit were used. WebThese tables show in situ (SPT) and laboratory (direct shear) tests results. Locations of sampling in the city are shown in Figure 1. Then, based on statistical validations, two equations were derived to estimate internal friction angle, based on SPT number for two soil types (GC, GW). In order to use Table 2 and Table 3, some points must be ...
