İki Tabakalı Zemin Profilinde Kazık Temellere Gelen Deprem Yüklerinin Eşdeğer Statik Yük Hesabı

Bu çalışmada, tabakalanmış suya doygun kil ve gevşek kum zeminlerde inşa edilen kazık gruplarına etki eden dinamik yüklerin statik yükler cinsinden uygulanabilirliği incelenmiştir. İki tabakalı zeminlerde oluşturulan kazık temellere üç farklı büyüklükte deprem yükü uygulanmış ve kazıkların yapmış oldukları deformasyonlar belirlenmiştir. Deprem etkisi altında kazık grubunun deformasyonlarının belirlenmesi için iki boyutlu Plaxis programının dinamik modülü kullanılmıştır. Analiz sonuçlarından geri hesap yöntemi ile kazık grubuna aynı deformasyonları yaptıracak eşdeğer statik yükler hesaplanmıştır.

Anahtar Kelimeler:

Kazık temel, Deprem yükü, Eşdeğer statik yük

Equivalent Static Load Calculation of Earthquake Loads Acting on Pile Foundations in the Two Layered Soil Profile

In this study, the applicability of equivalent static loads instead of dynamic loads acting on pile groupsconstructed in stratified saturated clay and loose sand was investigated. Three different earthquake loads wereapplied to pile foundations created in two layered soil and deformations of the piles were determined. Dynamicmodulus of the two dimensional Plaxis software was used to determine deformations of pile groups underearthquake effects. Equivalent static loads which gives the same deformations was calculated by back calculationmethod from the results.

Keywords:

Pile foundation, Earthquake load, Equivalent static load,
