difficult in sampling and indoor phisico-mechanical testing in hard weathered granite

the high pressure pressuremeter tests are carried out; and some valuable results in engineering are obtained. Results indicate that there are some difference in the correlation of the test between clay and weathered granite because of the differential weathering in horizontal direction in weathered granite; but there also exist some linear relationships between the ground bearing capacity and the measuring point depth
