(2) The crest elevation does not meet the requirements of the code in the standard. (3) The discharge valve damage. (4)The dam downstream energy dissipation facilities. The identification of the dam belongs to the three kind of dam. PS reservoir reinforcement design is according to the actual project preliminary design, the main contents include the calculation of stability against sliding of dam, dam foundation stress posite, spillway discharge capacity and energy dissipation and other parts. Calculation on stability against sliding of gravity dam is an important issue in the design, its purpose is to check dam along the interface between dam and foundation stability against sliding of dam safety, using the formula for judging whether meet the requirements of stability against calculation of dam in some cases do not meet the requirements of stability against sliding. Stress analysis to test the dam in construction and using period whether meet the strength requirements, use of material mechanics method testing stress whether meet the calculation of dam in some cases do not meet the requirements. Spillway flow capacity calculation and energy dissipation calculation based on design code for Spillway SL2532020 calculation, to meet the requirements. The final project reinforcement design, which does not meet the requirements of operation and meet the design requirements, the dam is strengthened. Key words: antisliding stability, stress posite, flow capacity and energy dissipation. 河北工程大學(xué)畢業(yè)設(shè)計(jì)（論文） 1 目 錄 1 綜合說(shuō)明 ................................................................................................................................... 1 工程概況 ................................................................................................................................. 1 水文 ................................................................................................................................. 1 流域概況 ................................................................................................................ 1 氣象 ...................................................................................................................... 1 水文 ...................................................................................................................... 2 泥沙 ...................................................................................................................... 2 工程地質(zhì)條件 ................................................................................................................... 2 結(jié)論及建議： ................................................................................................................. 2 工程除險(xiǎn)設(shè)計(jì) ................................................................................................................... 3 2 水庫(kù)大壩現(xiàn)狀情況校核 ............................................................................................................... 4 正常蓄水位下的壩體抗滑穩(wěn)定計(jì)算與壩基處應(yīng)力計(jì)算 ....................................................... 4 主壩抗滑穩(wěn)定計(jì)算與壩基應(yīng)力計(jì)算 .......................................................................... 4 副壩抗滑穩(wěn)定計(jì)算與壩基應(yīng)力計(jì)算 .......................................................................... 8 溢流壩抗滑穩(wěn)定計(jì)算與基應(yīng)力計(jì)算 ........................................................................ 10 設(shè)計(jì)洪水位下的抗滑穩(wěn)定計(jì)算與壩基應(yīng)力計(jì)算 ............................................................... 12 主壩抗滑穩(wěn)定計(jì)算與壩基應(yīng)力計(jì)算 ........................................................................ 12 副壩抗滑穩(wěn)定計(jì)算與壩基應(yīng)力計(jì)算 ........................................................................ 14 溢流壩抗滑穩(wěn)定計(jì)算與壩基應(yīng)力計(jì)算 .................................................................... 15 校核洪水位下的抗滑穩(wěn)定計(jì)算與壩基應(yīng)力計(jì)算 ............................................................... 18 主壩抗滑穩(wěn)定計(jì)算與壩基應(yīng)力計(jì)算 ........................................................................ 18 副壩抗滑穩(wěn)定計(jì)算與壩 基應(yīng)力計(jì)算 ........................................................................ 20 溢流壩抗滑穩(wěn)定計(jì)算與壩基應(yīng)力計(jì)算 .................................................................... 22 地震情況下正常蓄水位時(shí)的壩體抗滑穩(wěn)定計(jì)算與壩基處應(yīng)力計(jì)算 .................................... 24 主壩抗滑穩(wěn)定計(jì)算與壩基應(yīng)力計(jì)算 .....................................................
