It is proved that polypropylene fiber concrete performs well in resisting impact , abrasion and crack , and thus well applicable in sandy flow region characterized in high speed and turbulence , such as the filling & emptying culvert of shiplock , etc
表明聚丙烯纤维混凝土具有良好的抗冲耐磨性能和抗裂性能，可较好地应用于船闸输水廊道等处于高速、紊乱、含沙水流区。
The operation measures for controlling over - filling ( over - emptying ) are feasible ; the hoisting loads of valve and miter gate are less than their design values respectively ; but , there exists cavitation phenomenon needed to pay attention to the first crossover culvert when the value is near and after whole opening
控制超灌（泄）操作方式可行；阀门、人字门启闭力均小于设计值；阀门接近全开至全开后，输水廊道第一分流口有空化现象。
