| Summary: | The correlations of the three rock parameters, in relation to the construction of the Pahang-Selangor-State Raw Water Transfer (PSRWT) Project, were investigated during this undertaking. The purpose, of the Pahang-Selangor-State Raw Water Transfer Project (PSRWT), is to facilitate the transportation of raw water, from the Semantan River to the Selangor/Kuala Lumpur area, by way of a domestic and industrial transfer tunnel, to evade the occurrence of water shortages. From the study area in the Langat district of NATM-4, rock samples were obtained from 16 tunnel distances, for the execution of three tests: the impact strength test, the slake durability test, and the uniaxial compressive strength test. The objective of these tests is to determine the mechanical properties of the highly weathered granite rocks, and the correlation between the impact strength index, the slake durability index and the uniaxial compressive strength. According to the results from these tests, in terms of high impact loading durability, slake toughness and uniaxial compressive force, the slightly weathered rocks portrayed high strength, while the highly weathered rocks portrayed significantly lower strength. This investigation also revealed that the correlation between the impact strength index, the slake resilience index and the uniaxial compressive strength is directly proportional. The evaluation of rock strength, often calls for physical testing, as rock strength is closely related to the mechanical properties of the rocks concerned. |
