喷射混凝土护壁法是六十年代迅速发展起来的一种新型支护结构。近年来正日益广泛地应用于桥梁基础工程中,但是在理论和工艺上还不够完善,笔者不久前曾著文对喷层厚度进行过探讨,本文将侧重对桥梁基础开挖时护壁的设计与施工提出一点建议,以供参考。 Sprayed concrete wall protection law is the rapid development of a new type of supporting structure in the sixties. In recent years, it is increasingly widely used in bridge foundation engineering, but its theory and technology are not perfect enough. The writer recently discussed the thickness of shotcrete layer. This paper will focus on the design and construction of the protective wall Construction made a little suggestion for reference.
