Abstract

Bu çalışmada farklı silt türü zeminlerin likit limit değerleri Casagrande ve koni penetrometre deneyleri ile farklı boşluk oranı değerleri için belirlenmiştir. Elde edilen sonuçlara göre, zeminlerin boşluk oranının likit limit değerleri üzerinde önemli ölçüde etkiye sahip olduğu görülmüştür. Boşluk oranı etkisi ve operatöre bağımlı etkinin minimize edilmesi için koni penetrasyon deneyinin Casagrande deneyine kıyasla avantajlı olduğu belirlenmiştir. Boşluk oranı ve likit limit değerleri arasındaki ilişki zeminlere göre farklılık göstermektedir. Bu sebeple boşluk oranı değişime bağlı likit limit değerinin kestirimine yönelik genel bir bağıntının kullanımı önerilmemiştir. Bunun yerine, boşluk oranındaki değişim için zeminlerin ayrı olarak test edilmesi önerilmiştir.
