COMPARISON OF CORRECTED N VALUES BETWEEN SNI 4153:2008 WITH OTHER METHODS IN STANDARD PENETRATION TEST

Abstract

The research aims to compare the (N1)₆₀ values between SNI 4153:2008 and other methods in the SPT for 3 sites for the Civil Engineering Laboratory Building at Unika Santu Paulus Ruteng. The depth of SPT Site 1 (S1) is 9 meters where N_field 5-66, S2 8.55 meters and N_field 6-52, and S3 8.10 meters with an N_field value of 4-51. N₆₀ values ??at S1 6-79, S2 7-62, S3 5-66. Correction factors C_E = 1, C_R = 1, C_D = 1 and C_S = 1.2.  is obtained by correlating SPT data to calculate the C_N value based on the . N1)₆₀ S1 SNI 4153:2008 10.68-135.28; Liao and Whitman (1986) 31.84-271.32; Skempton (1986) 11.59-145.65; Tokimatsu and Yoshimi (1983) 13.87-171.13; Seed et al (1975) 16.87-184.83; Peck et al (1974) 12.71-144.33, Bazaraa (1967) 21.02-235.98. (N1)₆₀ S2 SNI 4153:2008 12.46-106.90; Liao and Whitman (1986) 37.15-224.89; Skempton (1986) 13.52-115.24; Tokimatsu and Yoshimi (1983) 16.18-135.82; Seed et al (1975) 19.68-148.73; Peck et al (1974) 14.83-115.54, and Bazaraa (1967) 24.52-190.18. (N1)₆₀ S3 SNI 4153:2008 8.90-114.64; Liao and Whitman Method (1986) 26.54-255.83; Skempton (1986) 9.66-123.76; Tokimatsu and Yoshimi (1983) 11.56-146.37; Seed et al (1975) 14.06-163.09; Peck et al (1974) 10.59-125.92, and Bazaraa (1967) 17.51-208.49. Comparison of (N1)₆₀ values ??are SNI 4153:2008 vs Skempton (1986) = 1:1.08; SNI 4153:2008 vs Peck et al (1974) = 1:1.13; SNI 4153:2008 vs Tokimatsu & Yoshimi (1983) = 1:1.29; SNI 4153:2008 vs Seed et al (1975) = 1:1.48; SNI 4153:2008 vs Bazaraa (1967) = 1:1.88; SNI 4153:2008 vs Liao & Whitman (1986) = 1:2.50.
