In　order　to　study　the　special　engineering　geologic　behaviors　of　sandy　strong-weathered　granite　and　reasonably　determine　the　values　of　its　bearing　capacity　and　deformation　modulus,　based　on　the　results　of　loading　test　in　site,　pressuremeter　test　and　standard　penetration　test(SPT)　about　sandy　strong-weathered　granite　in　Xiamen,　the　relations　among　bearing　capacity,　deformation　modulus　and　standard　penetration　test　were　discussed.　The　quantitative　model　about　the　bearing　capacity,　deformation　modulus　of　sandy　strong-weathered　granite　and　the　blow　counts　of　standard　penetration　test　were　proposed　to　determine　relational　parameters.　Through　analyzing　the　test　results,　the　bearing　capacity　value　of　sandy　strong-weathered　granite　should　be　determined　by　the　relational　equations　of　the　measured　values　of　standard　penetration　test　and　the　characteristic　values　of　subgrade　bearing　capacity.　The　characteristic　values　of　bearing　capacity　f　ak　were　over　600　kPa　and　increased　more　than　20　per　cent,　compared　to　the　last　generally　provided　foundation　bearing　capacity.　The　deformation　modulus　were　between　30-50　MPa,　but　the　last　provided　deformation　modulus　were　larger　than　50　MPa,　so　we　should　pay　attention　in　the　engineering　design.　The　analysis　of　experiment　results　showed　that　it　was　effective　to　determine　the　values　of　its　bearing　capacity　and　deformation　modulus　by　the　proposed　method.
