Boreholes were drilled to examine the depth of the crushed stones after soil improvement. One of the borehole logs is shown in Fig. 18.8.The stones were found to be present up to 9 m, in which the top 5 or 6 m was densely packed, whereas the remaining 4 or 5 m was embedded in clay.Below the crushed stone layer were a silty gravel layer and the weathered sandstone layer.

2015-6-4 Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but
