| dc.description.abstract | Soft quaternary deposit are widely found in Seberang Prai Selatan, Penang which consist of marine clay, silt and few thin layers of sand. But its characteristic and data was scarcely found. Due to active development on the area laid by quaternary deposit, construction the soft ground is becoming unavoidable despite its problematic character. Since soil characterisation are most essential for preliminary assessment before substructure design, adequate information of the subsurface condition is essential. Seismic soil investigation had been done to provide a reliable characterization of the soft marine deposits using in-situ Multichannel Analysis of Surface Wave consist of Active MASW, Passive MASW, Hybrid MASW and Seismic Cone Penetration Test (SCPT) to developed for site specific data of quaternary deposits of Penang. One dimensional in-situ shear wave velocity profiling described a heterogeneous layer of clay material ranged in 20 m/s to 180m/s from top layer until 15m depth and sandy soil layer with Vs ranged in 180m/s to 360 m/s at 15m to 30m depth. The shear wave velocity were used to determine the soil material had been compared with borehole lithology and SPT-N value. The values is consistent with the lithology and SPT-N value from bore log. Therefore, the range of shear wave velocity are valid and applicable for Seberang Prai Selatan quaternary deposit. Relationship between proposed 4 methods developed where Active MASW and SCPT method show weak relationship while Passive MASW and Hybrid MASW show strongest relationship. Hybrid MASW, a combination of Active and Passive MASW, show clear advantage for characterisation at deeper region compared to SCPT methods due to SCPT limited ability to penetrate hard soil. Active MASW captured high frequency noise which is limited to shallow region only. Therefore, it can be concluded that Hybrid and SCPT are reliable method for characterisation. Based on Vs30 from Hybrid MASW, Seberang Prai Selatan soil are classified as Site D and E. Combined shear wave velocity of Hybrid MASW and SCPT were used to determine the dynamic properties of Seberang Prai Selatan. The initial small strain stiffness or initial shear modulus described to be in range of 20 MPa to 50 MPa for clay soil at top to 15m depth and 50 MPa to 200 MPa for sandy soil at 15m to 30m depth. The elastic modulus ranged in 10 MPa to 40 MPa for the clayey soil and 20 MPa to 200 MPa for the sandy soil | |
