挤压式边墙施工法在混凝土面板坝工程中的应用

在混凝土面板坝的发展过程中,上游坡面的施工始终是一个控制进度和影响质量的关键环节。巴西埃塔面板堆石坝创新了一种挤压式边墙坡面施工方法F 以替代传统工艺中的超填、 削坡、修整、碾压、坡面防护等工序,加快了进度,施工质量也有所提高。该方法得到国际坝工界的认可,在我国也有推广的前景。

Application of sidewall extrusion method to concrete face slab dam construction

With the development of concrete face slab dam, the upstream slope construction is a key factor affecting the schedule and quality of construction. A new method was created in the construction of Aita Dam, Brazil. So called "sidewall extrusion" was used instead of traditional one, which had the steps of earth filling, scaling, refitting, rolling and revetment. The new method may quick up the schedule and improve the quality. It was approved by international association of dam construction and will be spreaded in our country.
