Ezperimental Research on Migration Character of Fascine Object s Underwater Falling
Fascine object is a set of engineering that people summarize and develop in the long-term struggle against the flood of the Yellow River. The flood is rapid and the stream has complex structure near groin. Unit in charge of construction and design are interested in motion characteristics, states of force reception and stationary estimate of fascine object. On the basis of experimental study, the authors analyze the migration character of fascine object s underwater falling, and draw the conclusion: ①Through float unit weight test and quiet coefficient of friction testing, get the quiet coefficient of friction of type I, type II railway carriage or compartment at the water of pillow and underwater terms,②According to different rivers terms, many group general to take observation of model test and survey data analysis, get the sink skew characteristic of fascine object in water, though the regression analysis and dimensional analysis, fit and get the function relational expression of non-dimensional random variable gS/V2 and independent variable h/H.
