The hydraulic putation has been that the sluice designs the most fundamental middle job working , has passed in and out of a pattern and had designed rate of flow by the fact that he is based on a sluice, may ascertain general brake hole clear width. 河北工程大學(xué)畢業(yè)設(shè)計（論文） 1 And ascertain out the proper hole number, the stream ability and the dimension canceling out each other energy equipment are needing a sluice gate in leaking time different open , the brake hydraulic putation is deciding the sluice scale in short ,to a great extent under responding to according to the condition designing water level. Irrigation works is calculated (defending against design oozing) , should ascertain out sluice lower levels building reasonableness underground outline and economy dimension by the fact that relevant to brake base peration secretly schemes against, checking calculation brake room stability. The maximal water level transfusion is calculated ought to have adopted lower reaches is bad , proportion law designs out whose first step underground outline and dimension first according to the straight line. After tier of building design tends to finalization of design high and low brake room, use resistance modulus to follow parallel precise secretly scheme against again. The sluice structure calculates the middle designing a job mainly all together in brake room. The structure needing to ascertain the brake room for this purpose , first is posed of , the scheme uses a dimension to require that the experience data first step designs out their main part later in the light of with arrangement. Third steps are posed of structure again to every giving structure if intensity, stability and stiffness secretly scheming against to verify every bearing the weight of a ponent satisfy design demand one by one, are more prudent than ascertaining out whose load and possible bination condition before the structure being in progress to various structure secretly schemes against.
