摘　　要：某工程为南水北调中线的穿河建筑,针对该河的南支与北支河道进行防冲墙的施工设计。结果显示,南支河道防护墙断面的冲刷深度均比施工后的冲刷深度要大,施工前后该河道防护墙断面的冲刷深度相差1.35m。北支河道防护墙断面施工前后的河道防冲墙的冲刷深度平均相差6.88m。表明所研究的河道防护墙施工方法能有效增强防护墙的透水防冲性能,研究成果可为今后穿河建筑物的防护加固处理提供参考与借鉴。A certain project is the crossing river construction of the middle line of the South-to-North Water Diversion project.This study carried out the construction design of anti-impact wall for the south branch and the north branch of the river.The results show that the scour depth of the south branch river protective wall section is larger than that after construction,and the difference of scour depth of the south branch river protective wall section before and after construction is 1.35m.The average difference of scour depth of the river is 6.88m before and after the construction of the northern branch of the river.The results show that the construction method of river protective wall can effectively enhance the permeability and anti-impact performance of the protective wall.The research method provides practical reference value for the protection and reinforcement treatment of river crossing buildings in the future.
