1、設(shè)計(jì)總說(shuō)明PS水庫(kù)位于河北省沙河市境內(nèi)，屬海河流域滏陽(yáng)河系沙洺河支流。本工程存在的主要問(wèn)題如下：(1)大壩基礎(chǔ)抗滑不滿足要求，壩體高水位時(shí)滲漏嚴(yán)重。(2)壩頂高程在不滿足規(guī)范要求。(3)放水洞閘閥損壞。(4)大壩下游無(wú)消能防沖設(shè)施。經(jīng)鑒定大壩屬于三類(lèi)壩。PS水庫(kù)除險(xiǎn)加固設(shè)計(jì)是根據(jù)實(shí)際工程進(jìn)行初步設(shè)計(jì)，主要內(nèi)容包括壩體的抗滑穩(wěn)定計(jì)算，壩基應(yīng)力復(fù)合，溢流壩過(guò)流能力及消能計(jì)算等幾個(gè)部分。壩體抗滑穩(wěn)定計(jì)算是重力壩設(shè)計(jì)的一項(xiàng)重要內(nèi)容，其目的是驗(yàn)算壩體沿壩基面的抗滑穩(wěn)定安全度，利用公式判別大壩是否滿足抗滑穩(wěn)定要求。經(jīng)計(jì)算得大壩在某些工況下不滿足抗滑穩(wěn)定
2、要求。應(yīng)力分析的目的是檢驗(yàn)壩體在施工和運(yùn)用期間是否滿足強(qiáng)度要求，利用材料力學(xué)的方法檢驗(yàn)應(yīng)力是否滿足要求。經(jīng)計(jì)算得大壩在某些工況下不滿足要求。溢流壩過(guò)流能力驗(yàn)算及消能計(jì)算依據(jù)《溢洪道設(shè)計(jì)規(guī)范》SL253-2000計(jì)算。經(jīng)計(jì)算得滿足要求。最后進(jìn)行除險(xiǎn)加固方案設(shè)計(jì)，使不滿足要求的工況滿足設(shè)計(jì)要求，使大壩得到加固。關(guān)鍵詞：抗滑穩(wěn)定、應(yīng)力復(fù)合、過(guò)流能力及消能計(jì)算。GeneraldescriptionofdesignPSreservoirinHebeiprovinceShahecitywithintheboundaries,theHaiheRiverV
