| This paper presents the results of plate loading test and discontinuum analysis, carried out to study the deformation behaviour and determine the deformation modulus of !rletamorphic andesitic tuff found at the site of a underground oil storage facility in Korea. In the plate loading test, the maximum pressure of 14MPa was applied to the bedrock by using a flat jack(1m in diameter) and the rock anchor system for the reaction against the applied pressure. The values of deformation modulus obtained from this test were compared with those of laboratory test, biaxial test and pressuremeter test. The deformation modulus from plate loading test was generally about half of the intact rock modulus, and the mass modulus of the bedrock at the test site may be affected by discontinuities and ranges between 25 and 350pa. Discontinuum analysis was also performed to simulate plate loading test and study the influence of discontinuities on the deformability of rock mass by simulating the presence of joints at the test area. |
