Soil Characteristics of Padma Multipurpose Bridge

Padma Multipurpose Bridge is situated on a section of the river where soil condition highly heterogeneous and intermixed with different layers, for which pile design was critical part. This paper describes properties ground profiling Bridge. Different types field laboratory tests were carried out to obtain accurate parameters profiles along whole alignment bridge. Standard Penetration Tests, Cone grain size analyses conducted classifications profiling. Flat Plate Dilatometer High Pressure Self-Boring Internal Friction Tests performed stiffness layers shear strength in conditions. Cross-hole Seismic Tomography Geophysical executed seismic waves dynamic modulus each layer. Gel Push Soil Sampling technique used collect undisturbed samples sandy soils get stress–strength-dilatancy characteristics through tests. The classified into three Units some sub-units based SPT-N value. finalized both test results. possible measurement
