A series of in-situ simulated tests and geotechnical tests are completed in big trough and medium trough under the condition of controlling the relative density and moisture of the Taklamaka desert sand in laboratory. Then some data and indexes such as static point resistance qc of cone penetration test
allowable bearing capacity pa
angle of internal friction ?
relative density Dr
modulus of deformation E0.01 etc. are got. On the basis of these data
some correlations including qc vs. pa
qc vs.?
qc vs. Dr
qc vs.E0.01 and digital forms applied for desert are given. All these are accumulated experience for application of cone penetration test on desert foundation investigation.
