In order to apply and disseminate static cone penetration test(CPT) technology in desert investigation

a series of in-situ stimulated test and soil engineering test are carried out in big trough and medium trough under the condition of controlling relative density and moisture content in laboratory. And some indexes of Taklamakan desert sand

such as static point resistance

standard penetration test(SPT) blow count N

angle of internal friction etc. are obtained at the same time. Through analysis and linear regression

it gives two equations of - and N- and their coordination. All these are accumulated experience for ground engineering investigation of desert oil field..
