Abstract

Abstract

Following the technique proposed by Muki Sternberg, the second kind Fredholm. s integral equation is deduced to solve the interaction factors between long-short piles. Using the principle of superposition a foundation with longshort piles is calculated. Compared with the results obtained using other methods by routine theory of elasticity, it shows that the strengthening effects of intervening piles on pile group settlement and individual pile load sharing are obvious. Finally, an extensive parametric analysis is made to study the foundation with long-short piles. The numerical analysis shows that the present method can be readily used to analyse large pile groups.
