【文章內(nèi)容簡介】 ent safe, suitable, economy, should be familiar with and analyse various kinds of materials at first, for instance topographical, geological situation, each about high Cheng, characteristic water level and corresponding flow, ect, then according to floodgate location, topography, geology, rivers, etc, terms and every building of function, characteristic, use demanding to confirm the pivot is decorateds of the pivot this, acplish the structure pactness, rational, coordinates, beautiful. conservancy is calculated: Including floodgate hole design, is it can is it wash the design, prevention of seepage drain off water and design to defend to disappear mainly. ⑴ The hole is designed in the floodgate give design flow definitely 河北工程大學(xué)畢業(yè)設(shè)計（水利水電工程） 第 8 頁 共 69 頁 confirm according to sluice form and materials that draft above floodgate hole clear width and suitable floodgate hole count at first, then checking putations plan floodgate hole size pass flow satisfied with the requirement of releasing floodwater for the first time. ⑵ Disappear and can defend and print designing for dispel water flow through energy of floodgate,is it disappear strength pool, sea overflow and defend and wash the trough to design. ① Disappear in the strength pool calculate in design water storage level under the terms, gate turn on in various kinds of form, operating mode of operation and hole of floodgate, one pair of holes is turned on symmetrically, three holes open and different flow of letting out while opening the height at the same time,confirm whether to need to set up and subdueing the strength pool or not. If is it design to need, want according to condition of can disappearing,is it disappear depth, strength of pool to calculate, thickness of the length baseplate and construction material used. ② The sea overflowing disappear strength pool can dispel rivers 50% energy,other energy all over the place to dispel from sea,according to different letting out amount of the sluice,confirm long degree and construction material of sea. ③ Defend and wash the trough calculate sea overflow end wash hole depth, is it wash trough section form and size to defend to design. ⑶ The prevention of seepage drains off water and designs: Draft the underground outline line at first, confirm the length tentatively, then confirm the floodgate room baseplate, length of the bedding and material sequentially, design and strain layer and drain off water in the hole position instead, calculate the base osmotic pressure of the floodgate finally, draw the distribution map of the osmotic pressure. floodgate room is decorated and floodgate room stability is calculated: ⑴ Confirm the size of the outline line of floodgate room confirmed the floodgate room is always wide by the water conservancy condition, floodgate high Cheng, floodgate mound, gate, pattern, size and floodgate 河北工程大學(xué)畢業(yè)設(shè)計（水利水電工程） 第 9 頁 共 69 頁 room top structure job bridge, traffic bridge, open and close pattern and size of the equipment of baseplate very. ⑵ The floodgate room is calculated steadily choosing the unit of calculating, build one according to finishing, normal conservation storage one, normal conservation storage issue add special to is it make up three opeerating mode checking putations floodgate room resist slippery stability and ground bear the weight of strength checking putations to load, distribute state and subside to ground stress difference carry on putational analysis, judge sluice ground meet strength of bearing the weight of, is it slip steady and out of shape requirement to resist. ⑶ The deep layer of floodgate room is slipped and the subsiding amount of ground is calculated according to design soil physics characteristic index that materials provide, checking putations foundation is it drive some ground soil slip to the low reaches to happen under loading function, confirm whether to carry on the subsiding amount of the ground to calculate or not. sides join buildingbank,structure pattern, wing of wall, assign and the stability is calculated: ⑴ By physical dimension and ground terms, floodgate of room, confirm bank, level, wing of wall assign the pattern and size of section. ⑵ Building an two kinks of operating modes of one and normal conservation storage according to finishing, the ground on other bank, wing wall bears the weight of strength, basis heavy minimum stress ratio count bottom surface of the base is it calculate to go on steadily to slip to resist most. ⑶ Facilities of prevention of seepage in the wing wall of the upper reaches and pumping equipment on the downstream wing wall are designed. structure of floodgate room is calculated: ⑴ Mound stress analysis of the floodgate: Regard as floodgate firm to connect cantilever beam at baseplate by mound, regard the bination surfaces of the mound of the floodgate and baseplate as and calculate the chain of mand, separately according to use issue (gate is it block water to shut off ) and overhaul issue two 河北工程大學(xué)畢業(yè)設(shè)計（水利水電工程） 第 10 頁 共 69 頁 kinds of operating modes , mound vertical direct stress of horizontal section, shearing stress, trough stress of the door, mound bottom level sectional side direction stress of mound bottom while calculating, analyse result of calculation, is it mix muscle design to go on. ⑵ Stress analysis of the baseplate: Make gate as the boundry, divide baseplate into two part from head to foot, fetch single wide lath analyse in two part central vertical rivers direction separately. Accord to finishing and building one and using the operating mode of an improved variety, calculate the load on function and lath. Including the baseplate conducts oneself with dignity,china, mound and top structure are heavy, raise pressure and uneven to cut streng
