Abstract Research purposes: By the statistic analysis of the physical and mechanics indexes of the granitoid residual soil Line R2 in Dongguan，the physical and mechanical properties of the granitoid residual soil are found out，the relation between the physical and mechanical indexes is set up and some measures and recommendations on the engineering in granitoid residual soil area are offered．

Research conclusions: ( 1) The particle composition of the granitoid residual soil in dongguan has features of big ends， small middle part，big natural pore，small liquidity index，strong shear strength，big compressive coefficient，small compressive modulus and small the expansive property． ( 2) There is a lineal relation between the natural pore and the compressive modulus． ( 3) The in － situ test should be used along with the indoor test for the investigation．

Key words： dongguan city granitoid residual soil physical and mechanical properties
