睢宁二站是南水北调东线第五级泵站，是以调水为主，兼有农业灌溉、航运、排涝和防洪等综合性能的大型泵站，是南水北调东线建筑物中地震烈度最高、扬程最高、基坑最深、单块底板面积较大的泵站。该泵站结构采用肘型进水流道、虹吸式出水流道的块基型结构，采用真空破坏阀断流。现着重从泵站结构布置、侧向抗滑稳定措施、结构计算方法、裂缝控制、基坑支护等方面进行结构计算、设计。该泵站计算方法对类似工程具有一定的参考价值。
睢寧二站是南水北調東線第五級泵站，是以調水為主，兼有農業灌溉、航運、排澇和防洪等綜閤性能的大型泵站，是南水北調東線建築物中地震烈度最高、颺程最高、基坑最深、單塊底闆麵積較大的泵站。該泵站結構採用肘型進水流道、虹吸式齣水流道的塊基型結構，採用真空破壞閥斷流。現著重從泵站結構佈置、側嚮抗滑穩定措施、結構計算方法、裂縫控製、基坑支護等方麵進行結構計算、設計。該泵站計算方法對類似工程具有一定的參攷價值。

Suining pump station ò is the fifth stage lift water cascade station along the Eastern Route of the South-to-North Water T ransfers. The project is a comprehensive hydropower project as water diversion is its main purpose and combining irrigation, shipping, and flood and wa-terlogging control. It is the pump station with the highest earthquake intensity, the highest lift head, the deepest foundation pit, larger block of singlefloorareaofthebuildingsalongtheEasternRoute.Theblock-basedstructureinthepumpstationiswiththeelbow-shapedinletpassage and siphon outlet conduit. The vacuum-breaking valve is applied in the station. T he paper has calculated and designed based on the aspects of structural arrangement, measures of lateral stability, structural calculation and analysis, limiting cracks, retaining and protection of foundation pitsofthepumpingstation.Theanalysiscanbeareferencetothestructuralreinforceddesigninthesimilartypeoflarge-scaleblock-basedpum-ping stations.
