摘要
RCC,RCD两种工艺的廊道施工常常制约大坝整体的上升速度,冈此改进灌浆廊道的设计对加快大坝整体的施工进度显得十分重要。本文介绍了倒U型预制廓道和方型廊道,并对两种廊道结点应力和施工进行对比。
The gallery construction of RCC and RCD often restricts the damming velocity, the improving design of grouting gallery is very important for accelerating construction progress of dam. The paper introduces the inverted U prefabricated gallery and the square - shaped gallery, compares their junction point, stress and the construction.
