The soil layer of representative is mostly argillic horizon；And resistance is big, frictional resistance is smaller, excess pore water pressure very little, curve are in saw jumpy
Dentation is then sand.
(2) each soil layer interface depth is accurately determined by concepts such as critical depths.Static sounding is from earth's surface at the uniform velocity penetration process
In, Cone resistance is gradually increased (crust layer influence except), to certain depth (critical depth) after just reach a more steady state value,
Critical depth and the more steady state value section of curve first are first layer；When probe is continued near injection to the second layer, resistance meeting of popping one's head in
By upper and lower soil layer joint effect and change, become larger or become smaller, universal law is positioned at the intermediate deep of curvilinear motion section
Degree is level depth, and the second layer also has more steady state value section, analogizes below.
