Question:
A scanline survey has been conducted on a rock slope with a length of 20 m at Gua Musang highway for rock slope stabilization purposes. The rock slope was classified as granite with weathering grade II (slightly weathered rock). Two boreholes were drilled at two locations denoted as BH1 and BH2 as shown in Figure Q2(d). Each borehole sample has a length of 1500 mm.?
(i) Determine the number of joints that intercepts with the scanline.
(ii) Measure the number of joint sets that forms on the rock slope.
iii) Calculate the rock quality designation (RQD) for borehole 1 (BHI).
(iv) Determine the rock quality designation (ROD) for borehole 2 (BH2).
(v) Compare your answer in Q2(d)(iii) and Q2(d)(iv). Identify the main factor that effect this result and discuss the consequences of this factor to the stability of the rock slope.
