In this study, a new spring plate was designed and investigated for its usability with the split set type friction bolts. According to the results of this study, remarkable active support pressures can be practically supplied by compression of the new spring plate during the insertion of the split sets. In addition to easy supply of the active support pressure owing to the insertion of the bolts, the energy absorption capacity can be highly improved by use of the new spring plate. Furthermore, the new plate design is remarkably advantageous against the nonaxial loading condition which is very wide in the bolted rock masses.

Bu çalışma kapsamında yeni bir yaylı plaka tasarlanmış ve split set türü sürtünmeli kaya saplamaları ile birlikte kullanılabilirliği incelenmiştir. Elde edilen sonuçlara göre split setlerin montajı esnasında yaylı plakanın sıkışması ile önemli seviyelerde aktif tahkimat basıncı pratik olarak sağlanabilmektedir. Saplama montajı ile kolayca sağlanabilen aktif tahkimat basıncına ek olarak yeni yaylı plaka kullanımının enerji emme kapasitesi değerlerini yüksek oranda artırdığı belirlenmiştir. Ayrıca, saplama yapılmış kaya kütlelerinde yaygın yaşanan eksenel olmayan yüklenme durumu karşısında da yeni yaylı plakaların kaya saplaması performansını artırması sebebi ile avantajlı olduğu görülmüştür.
