Abstract AR
من الضروري مقارنة معاملات الانضغاط (Cc) و إعادة الانضغاط (Cr) أثناء حساب استقرار الطبقات الطينية.
و عادة ما نحصل على هذه المعاملات تجريبيا باستخدام اختبار السرعة, و هذه تتطلب وقتا طويلا للقيا كما يتطلب إجراءات تجريبية حثيثة و مكثفة.
و هناك العديد من الأبحاث المنشورة في محاولة لإيجاد علاقة بين كل من Cc و Cr, إضافة إلى الكثير من المميزات التي يمكن أن تستخدم لمقارنة أنواع الطين المختلفة.
و من هذه المميزات : نسبة (OCR).
في هذه الدراسة نستقصي أثر (OCR) و نسبة الفراغ الأولية (eo) على عينات من الطين قبل اللدونة التي تم تحضيرها مخبريا تحت ضغوط مختلفة.
و قد قمنا بإجراء اختبار السرعة على هذه العينات, و من ثم حساب Cc و Cr.
و تشير النتائج إلى أن قيم Cc و Cr قد تأثرت بـ OCR و eo, و في معظم الحالات حصلنا على علاقة خطية.
و تعتبر هذه النتائج قيمة من الناحية الأكاديمية و العملية.
Abstract EN
Compression (Cc) and recompression (Cr) indices obtained from the oedometer test are necessary in settlement calculation for clayey soil layers.
However, the oedometer test takes a long time to measure the compression of clays.
This will lead to a very demanding experimental working program in the laboratory.
In the literature, a number of researchers have been looking for a possible relationship between Cc and Cr indices and general characteristics of clays.
A number of parameters appear to have an effect on the compression of clays.
One of these parameters is overconsolidation ratio (OCR).
In this study, the effect of OCR and initial void ratio (eo) on Cc and Cr indices of a low plasticity overconsolidated clayey samples, which were prepared in the laboratory under different isotropic pressures, was investigated.
Thus, the oedometer tests were performed on these samples, and consequently Cc and Cr indices were calculated.
The results indicate that Cc and Cr indices were influenced by OCR and eo, and, in most cases, a linear relationship between Cc and Cr indices was observed.
The results of this research can provide valuable contributions for academics and practitioners.
