Karasal iklimin ya\u015fand\u0131\u011f\u0131 b&ouml;lgelerde uygulanan kaya bulonlar\u0131nda donma-&ccedil;&ouml;z&uuml;nme sonras\u0131 zay\u0131flama nedeniyle ankraj kapasitelerinde de\u011fi\u015fim olabilir. Literat&uuml;rde donma-&ccedil;&ouml;z&uuml;nmenin kaya bulonu uygulamalar\u0131n\u0131n mekanik &ouml;zellikleri &uuml;zerindeki etkilerinin ara\u015ft\u0131r\u0131ld\u0131\u011f\u0131 &ccedil;al\u0131\u015fmalar yer al\u0131nmaktad\u0131r. Bu &ccedil;al\u0131\u015fmalarda genellikle malzemeler ba\u011f\u0131ms\u0131z olarak incelenmekte ve kaya bulonlu sistemler b&uuml;t&uuml;nc&uuml;l olarak yeterince ele al\u0131nmamaktad\u0131r. Bildiride bulon kaya i&ccedil;erisine enjeksiyonla ankraj edilerek olu\u015fturulmu\u015f kaya bulonlu numunelerde donma-&ccedil;&ouml;z&uuml;nmenin etkileri incelenmi\u015ftir. Ayr\u0131ca, kaya bulonlu numuneyi olu\u015fturan kaya ve enjeksiyon malzemelerinde donma-&ccedil;&ouml;z&uuml;nme sonras\u0131 meydana gelen de\u011fi\u015fimler ele al\u0131nm\u0131\u015ft\u0131r. &Ccedil;al\u0131\u015fmada kaya olarak riyodasit, bulon olarak &Oslash;12 nerv&uuml;rl&uuml; donat\u0131 ve enjeksiyon s\u0131v\u0131s\u0131 olarak su/&ccedil;imento oran\u0131 (S/&Ccedil;) 0,4 olan kar\u0131\u015f\u0131m se&ccedil;ilmi\u015ftir. Haz\u0131rlanan enjeksiyon, kaya ve kaya bulonlu numuneler 14, 56, 84 ve 140 donma-&ccedil;&ouml;z&uuml;nme &ccedil;evrimlerine tabi tutulmu\u015ftur. Enjeksiyon numunelerinde 90 &ccedil;evrim sonras\u0131 k\u0131r\u0131lmalar meydana geldi\u011fi i&ccedil;in bu &ccedil;evrimden sonra &ccedil;evrimler sonland\u0131r\u0131lm\u0131\u015f ve 84 &ccedil;evrime kadar yap\u0131lan deneyler de\u011ferlendirilmi\u015ftir. Laboratuvar deney sonu&ccedil;lar\u0131, donma&ccedil;&ouml;z&uuml;nme &ccedil;evrimlerinin kaya ve enjeksiyon numunelerinde fiziksel ve mekanik &ouml;zelliklerinde de\u011fi\u015fikli\u011fe neden oldu\u011funu g&ouml;stermektedir. Ayr\u0131ca, kaya bulonlu numunelerde ba\u015flang\u0131&ccedil;ta 49.935 kN olan &ccedil;ekme kuvvetinin 84 &ccedil;evrim sonras\u0131nda 34.628 kN&rsquo;ye d&uuml;\u015fmesi, donma&ccedil;&ouml;z&uuml;nmenin ankraj kapasitesini d&uuml;\u015f&uuml;rd&uuml;\u011f&uuml;n&uuml;n bir kan\u0131t\u0131d\u0131r. Sonu&ccedil; olarak, donma&ccedil;&ouml;z&uuml;nmenin kaya bulonu performans\u0131na olumsuz etki etti\u011fi ve tasar\u0131mda bu etkinin de\u011ferlendirilmesi gerekti\u011fi belirlenmi\u015ftir.</p>",
