Abstract

This paper aims to deal with the assessment of axial load capacity for cast in place pile foundations, which are made by the earth drill method, by using the data taken from Standard Penetration Tests (SPTs) and Piezocone Penetration Tests (CPTUs). These tests were carried out as part of the investigation program for P.N.G. Terminal-Power Plant, near Semani beach, in Hoxhara marsh, in the western part of Albania. The design of axial load capacity of piles is based on empirical formula using SPT and CPTU values. This study presents the results of axial load capacity analysis of cast in place piles by different analytical calculation methods, which are based on in situ tests results, and also referring to the Building Standard Law of Japan. In the end of our work, differences between calculations methods by using different in situ tests results are shown in tables and graphs.

Highlights

  • The construction site, where the Standard Penetration Test (SPT) and CPTU tests are carried out, is located in the area of Semani beach, near Fier city, Albania

  • The results of 416 SPT and 12 CPTU are considered during the axial load capacity analysis

  • Since the analyses of Axial Load Capacity of piles in this construction site are related to the data of SPT and CPTU tests, at first we dialed with the results of these tests, which were reported in the geological study

Summary

Introduction

The construction site, where the SPT and CPTU tests are carried out, is located in the area of Semani beach, near Fier city, Albania. The tests considered in this study, are executed according to the site investigation program at Terminal Power Plant The results of 416 SPT and 12 CPTU are considered during the axial load capacity analysis. SPT tests were carried out, as the primarily recommended tests for granular soils and other ground conditions
