The stiffness of a sedimentary soft rock, Sagamihara mudstone, was measured by the triaxial compression tests by using the local deformation transducer and it is compared, taking into account its strain level-dependency, with those from the seismic survey, the plate loading tests and the pressuremeter tests. Then, from the deformation of ground by excavation at the same site, the modulus of deformation was back-analyzed by three dimensional FEM and BEM, and was compared with the values obtained as above. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
