THE CORRELATION BETWEEN STATIC PILE CAPACITY AND DYNAMIC PILE CAPACITY IN DIFFERENT SITES IN BASRA CITY, CASE STUDY

Abstract

The present research concerns the correlation between the static pile test and the dynamic pile test of driven piles in Basra city by using two types of pile, which are the precast reinforced concrete piles and steel tube closed-end piles. 100 pile tests in the Majnoon oil field, which is located in the north of Basra City, Southern Iraq, are considered in this paper, which focuses on the ultimate pile capacity as the criterion in establishing the correlation between the two test types. The CAPWAP program was used in determining the dynamic pile capacity, while Davisson's method was applied as a criterion in estimating the ultimate pile capacity. The Results have shown that  a very strong correlation between the two types of pile tests and the dynamic pile tests, which gave  higher values of the pile capacity than the static pile capacity and the case method. Also, the results indicate that the damping factor of soils in dynamic tests showed some variation larger than the quake value from the values of the case method.
