| description | Indonesian government through the National Nuclear Agency (Batan) has
planned to build a nuclear power plants, with one interest area of site study of nuclear
power plants in Teluk Inggris-Tanah Merah, Airputih Village, Muntok District, Bangka
Barat Regency, Bangka Belitung Archipelago Province. Engineering geology condition is
not yet known in detail. Therefore, some researches are necessary to do to know the
engineering geology condition, especially the rock mass quality at this area in detail.
Engineering geology investigations is carried out by assessing the rock mass
quality and bearing capacity based on field observation and drilling data. The quality
and bearing capacity analysis were done by using classification of Rock Mass Rating
(RMR) (Bieniawski, 1989) and the Geological Strength Index (GSI) (Hoek, 1994).
The Rock mass at the study area was divided into four (4 ) units , namely Units
of Sandstone, Granite, Mudstone and Pebbly Sandstone. The RMR and GSI value in the
study area is influenced by the parameters of discontinuity space density, the slope of
discontinuity orientation, grade of weathering and groundwater conditions. From all
rock units, Granite Unit has the best quality which is showed by the average value of
RMR is 53 and GSI value is 66 with in 862.5 Ha large area. Based on RMR value of
Granite Unit can be estimated the range of cohesion values is between 0.2 - 0.3 MPa , the
friction angle is between 25o - 35o, and the allowable bearing pressure is between 280 -
135 T/m2. Based on GSI value of Granite Unit can be estimated the uniaxial compressive
strength value is 1.0465 - 183.8 MPa, tensile strength is between -0.0122 - -5.2625 MPa,
the rock mass strength value is 24.5244 - 220.351 MPa, and modulus of deformation with
a range 1.73 - 86.68 GPa. Based on the RMR and GSI value and bearing capacity of the
rock mass, the most appropriate location for the nuclear power plants site is Granite
Unit, where an area of approximately 393 Ha is the best location for the shallow
foundation of nuclear power plants with raft foundation type. |
