Correlation of uniaxial compressive strength between UCT and point load index of rock in Klang Valley
Uniaxial compressive strength (UCS) is one of the most important properties of rock that are widely used in geotechnical field. Since, the direct method to obtain UCS is expensive; Point Load Test (PLT) is the most commonly used method to estimate UCS. There are several general conversion factor sug...

| 要約: | Uniaxial compressive strength (UCS) is one of the most important properties of rock that are widely used in geotechnical field. Since, the direct method to obtain UCS is expensive; Point Load Test (PLT) is the most commonly used method to estimate UCS. There are several general conversion factor suggested such as by the ISRM. However, it is found that index-to-strength study is rock dependent and site specific. This research presents on the correlation of UCS between Uniaxial Compressive Test (UCT) and PLT in Klang Valley based on location and rock type. UCT and PLT were conducted on a total of 40 sets of Limestone and 45 sets of Granite rock. The correlation equation for each location are; UCS = 21.192 Is(50) + 4.1976 for Serdang Lama, UCS = 5.7239 Is(50) + 73.819 for Wangsa Maju, UCS = 13.326 Is(50) + 46.24 for Jalan Kepong, UCS = 8.1125 Is(50) + 12.344 for Cochrane, UCS = 1.7789 Is(50) + 39.112 for Jalan Stonor, UCS = 12.151 Is(50) + 19.04 for Bandar Malaysia South, UCS = 18.921 Is(50) – 0.7189 for Sungai Long, UCS = 3.9971 Is(50) + 21.322 for Balakong, UCS = 6.618 Is(50) + 19.938 for Sector C, Parkcity and UCS = 33.708 Is(50) - 43.029 for USJ 7, Subang Jaya.In addition, a regional map of correlation equation is produced for future references in obtaining the UCS from the PLT. |
