Evaluation Of Undrained Shear Strength Of Soil, Ultimate Pile Capacity And Pile Set-Up Parameter From Cone Penetration Test (Cpt) Using Artificial Neural Network (Ann), Md Ariful Hassan Mojumder

LSU Master's Theses

Over the years, numerous design methods were developed to evaluate the undrained shear strength, S_u, ultimate pile capacity and pile set-up parameter, A. In recent decades, the emphasis was given to the in-situ cone and piezocone penetration tests (CPT, PCPT) to estimate these parameters since CPT/PCPT has been proven to be fast, reliable and cost-effective soil investigation method. However, because of the paucity of a vivid comprehension of the physical problem, some of the developed methods incorporate correlation assumptions which might compromise the consistent accuracy. In this study, the Artificial Neural Network (ANN) was exerted using CPT data …

Estimation Of The Axial And Lateral Capacity Of Driven Piles From The Results Of Cone Penetration Test And Finite Element Analysis, Mohsen Amirmojahedi

LSU Doctoral Dissertations

Piles play an important role in transportation and bridges. They are used to resist axial and lateral loads transferred to them from structures, earth pressures, incline loads, vehicles, etc. In this study, the capacity of piles for axial and lateral loads is investigated.

The ultimate axial capacity of piles can be estimated using different approaches including static pile load tests, dynamic load tests, statnamic load tests, and static analysis based on laboratory tests (effective and total stress approaches) or in-situ tests (SPT, CPT, etc.). For each approach, different researchers have proposed different solutions for different soils and different piles. Mostly, …
