南水北调中线工程穿越沁河的建筑物型式为渠道倒虹吸,穿沁工程是南水北调中线工程总干渠河南省渠段黄河以北最大的建筑物,建筑物总长1212m,设计过水流量265m~3/s,加大流量320m~3/s,采用3孔钢筋混凝土箱形结构,单孔尺寸6．9m×6．9m。建筑物建基面高程84．0m,基础开挖深度高达27m,边坡大部分为砂质,且有河水、潜水及多层承压水的影响,因此工程施工中边坡稳定问题将是一个非常重要的问题,解决的好坏直接关系着工程的投资、进度,应引起高度的重视。
The South-to-North Water Diversion Middle Route works through Qinhe River as a type of inverted siphon. Chuanqin Project is the largest canal to the north of the Yellow River in Henan Province. The total length of the building is 1212m and the designed flow rate is 265m 3 / s , Increase the flow of 320m ~ 3 / s, the use of 3-hole reinforced concrete box-shaped structure, single hole size 6.9m × 6.9m. The elevation of the building surface is 84.0m and the foundation excavation depth is up to 27m. Most of the slope is sandy, and has the influence of river water, submersion and multi-layered confined water, so the slope stability problem in construction will be one Very important issues, the quality of the solution is directly related to the project investment, progress, should be a high degree of attention.
