27 Mei 2016/Diterima: 18 Oktober 2016 ABSTRACT The uniaxial compressive strength test is a destructive and time
consuming test. A number of non-destructive methods using portable
testing equipment are more applicable and easier to conduct. This
paper presents the results of a systematic approach to determine
the uniaxial compressive strength of rock material using the Schmidt
hammer rebound test. A total of five distinct locations (Graham
Coast, Davis Coast, Nanson Island, Danco Coast and Trinity Island)
were tested using the Schmidt rebound hammer test. Peninsula Antarctic
located at northwest of Antarctic region comprising of igneous and
metamorphic rocks. Statistical analysis of the results at 95% confidence
level showed the Schmidt rebound value of the Graham Coast ranges
from 40±1.7 to 41±1.3 with standard deviation of 8.2 to 6.4. The
rebound value for Davis Coast was 39±1.6 with standard deviation
of 7.7. Rocks from Nanson Island and Danco Coast have the Schmidt
rebound value of 54±1.7 with standard deviation of 8.0 and 36±1.3
with standard deviation of 6.2, respectively. The Schmidt rebound
value of rocks at Trinity Island ranges from 29±1.4 to 32±1.7 with
standard deviation of 6.8 to 8.1. Thus, the respective uniaxial
compressive strengths of rock materials from Graham Coast, Davis
Coast, Danco Coast, Nanson Island and Trinity Island were 73-108,
50, 59, 164 and 45-59 MPa. The respective ISRM
strength classification of rock materials of Graham
Coast, Davis Coast, Danco Coast, Nanson Island and Trinity Island
were strong (R4) to very strong rock (R5), medium strong rock (R3),
strong rock (R4), very strong rock (R5) and medium strong (R3) to
strong rock (R4). The results showed a mean of quantification of
rock material strength based on the Schmidt Hammer rebound test
in Antarctic Peninsula. Keywords: Rock material; Schmidt hammer rebound value; uniaxial compressive
strength ABSTRAK Ujian kekuatan mampatan sepaksi adalah ujian memusnah dan memakan
masa. Beberapa kaedah tidak-musnah yang menggunakan peralatan ujian
mudah alih adalah lebih diterima pakai dan mudah untuk dijalankan.
Kertas ini membentangkan keputusan menggunakan pendekatan yang sistematik
untuk menentukan kekuatan mampatan sepaksi bahan batu dengan menggunakan
ujian pantulan tukul Schmidt. Sebanyak lima lokasi (Pantai Graham,
Pantai Davis, Pulau Nanson, Pantai Danco dan Pulau Trinity) telah
diuji menggunakan ujian pantulan tukul Schmidt. Semenanjung Antartik
yang terletak di barat laut Wilayah Antartik terdiri daripada batuan
igneus dan metamorfik. Keputusan analisis statistik pada tahap keyakinan
95% menunjukkan nilai pantulan Schmidt pantai Graham berjulat dari
40±1.7 ke 41±1.3 dengan sisihan piawai sebanyak 8.2 ke 6.4. Nilai
pantulan pantai Davis adalah 39±1.6 dengan sisihan piawai sebanyak
7.7. Batuan dari Pulau Nanson dan Pantai Danco mempunyai nilai pantulan
Schmidt masing-masing sebanyak 54±1.7 dengan sisihan piawai 8.0
dan 36±1.3 dengan sisihan piawai sebanyak 6.2. Nilai pantulan Schmidt
untuk batuan di Pulau Trinity adalah dari 29±1.4 hingga 32±1.7 dengan
sisihan piawai sebanyak 6.8 ke 8.1. Oleh itu, kekuatan mampatan
sepaksi bahan batuan masing-masing dari Pantai Graham, Pantai Davis,
Pantai Danco, Pulau Nanson dan Pulau Trinity adalah 73-108, 50,
59, 164 dan 45-59 MPa. Pengelasan kekuatan ISRM bahan
batuan untuk Pantai Graham, pantai Davis, Pantai Danco, Pulau Nanson
dan Pulau Trinity masing-masing adalah kuat (R4) ke batuan yang
sangat kuat (R5), batuan sederhana kuat (R3), batuan kuat (R4),
batuan sangat kuat (R5) dan sederhana kuat (R3) ke batuan kuat (R4).
Keputusan ini menunjukkan satu purata kekuatan bahan batuan secara
kuantitatif berdasarkan ujian pantulan tukul Schmidt di Semenanjung
Antartik. Kata kunci: Bahan batuan; kekuatan mampatan sepaksi;
