Calculation of height and force of baffle wall style in comprehensive and gradual expanding stilling basin

The paper studied the calculation method of depth, height and force of comprehensive and gradual expanding stilling basin .According to hydraulic jump equation, weir flow theory and the result of previous research for length of hydraulic jump, conjugate depth and submerged coefficient in gradual expanding stilling basin,it analyzed the design method of comprehensive and gradual expanding stilling basin and researched the force of baffle wall style in accordance with momentum equation.The formula of wall height and force proposed by the paper is not only adaptable to the design of comprehensive and gradual expanding stilling basin but also to that of gradual expanding type and baffle wall style stilling basin.The calculation method is new and the process is simple.The precision meet the design requirements.
