Empirical Correlation between Standard Penetration Resistance (SPT-N) and Shear Wave Velocity (V<sub>s</sub>) for Soils in Metro Manila, Philippines
The measurement of the shear wave velocities (V<sub>s</sub>) of soils is an important aspect of geotechnical and earthquake engineering, due to its direct relation to the shear modulus (G), which in turn influences the stress–strain behavior of geomaterials. V<sub>s</sub> can...

| description | The measurement of the shear wave velocities (V<sub>s</sub>) of soils is an important aspect of geotechnical and earthquake engineering, due to its direct relation to the shear modulus (G), which in turn influences the stress–strain behavior of geomaterials. V<sub>s</sub> can be directly measured or estimated using a variety of onsite tests or in a laboratory. Methods such as downhole PS logging require boreholes and may not be logistically and economically feasible in all situations. Many researchers have estimated V<sub>s</sub> from other geotechnical parameters, such as standard penetration test resistance (SPT-N), by means of empirical correlations. This paper aimed to contribute to this subject by developing an empirical relationship between V<sub>s</sub> and SPT-N. Data from twenty sites in Metro Manila were obtained from geotechnical investigation reports. V<sub>s</sub> profiles of the same sites were also acquired using the refraction microtremor method. New empirical relationships were developed for all, sandy, and clayey soil types, using a non-linear regression method that is applicable for Metro Manila soils. Statistical evaluation and comparison of the proposed correlations with other previous works suggested the viability of the empirical model. |
