This paper make use of Shi-Men reservoir bottom mud to carry out flocculated framework phase batch experiment in static water‚ discuss every depth layer concentraction change with time and it’s interface settling velocity‚ and realize settling characteristic of Shi-Men reservoir mud.
By the results and analyses of this paper‚ when initial concentraction is about 70(g/L)‚ it can produce clear and visible interface‚ and observing interface down also know settling velocity. When constant concertraction region disappears, interface velocity would be suddenly down.
As concentraction between 70〜110(g/L), settling velocity decreases with time increases; concentraction between 110〜150(g/L), settling velocity of water depth 50(cm) is greater than settling velocity of water depth 200(cm). This paper also use Ratio Concentraction Method to estimate compression region concentraction.
key words：settling velocity、floccuated framework
