摘　　要：针对白马泾泵站的工程实际情况,结合地形、地质条件及边坡稳定要求,对泵站基础采取分期开挖,局部采用陡边坡开挖,加快了施工进度,减少了开挖工程量及投资。在泵房出水流道砼中掺入聚丙烯纤维并预埋冷却水管,有效控制混凝土裂缝的发生。Aiming at the engineering current situation of BaiMajing pump station,combined with the terrain and geological conditions and the slope stability requirements,we adopted the method of multi-stage excavation to pumping station foundation and the method of steep slope excavation partly,speeding up the construction progress,reducing the excavation quantities and investment.In the pump outlet conduit concrete,mixed with polypropylene fiber and pre-buried cooling water pipe can effectively control the occurrence of the concrete cracks.

关 键 词：泵站工程 基础开挖 裂缝控制
