摘　　要：近几年来,挤压式混凝土边墙施工技术在国外已经广泛应用于混凝土面板坝施工中。这项技术因其能明显提高垫层料的压实质量,以及简便、及时地提供上游坡面的防护等特点,已引起世界各国的广泛关注。我国在青海公伯峡水电站首先应用了这种新方法。虽然此项技术已应用于多个工程,但不同工程因其挤压边墙施工中挤压机存在的问题及改进方法不尽相同,相应的处理方式也存在差异。就边墙挤压机在马来西亚巴贡水电站工程的应用实例,简要阐述了边墙挤压机在混凝土面板坝施工中的应用。Over last years,concrete sidewall extruding construction technique has been widely applied in concrete face reckfill dam construction in other countries.This technique is more and more concerned by many countries in the world because it is used so as to significantly improve compaction of bedding materials and easily and properly provide protection for upstream slope face.This new method was firstly applied in Gongboxia hydropower station in Qinghai Province of China.This technique has been used for several projects,but respective treatment is different due to various problems in extruders used in sidewall construction and distinct improvements needed to be made for separate project.In this paper,in the case of Bakun hydropewer station in Ma- laysia,application of sidewall extruder in construction of concrete face rockfill dam is briefly described.
