摘　　要：膏溶角砾岩具有强度低、土质不均、局部压缩性高的特点,属于复杂的特殊软岩,以太行山隧道Z5标段的膏溶角砾地质特征为依托,对膏溶角砾岩的地质背景、成因、工程特性等进行了分析研究,并着重介绍了膏溶角砾岩的工程性能现场试验分析结果。Gypsum breccia, having such characteristics as low strength, heterogeneous quality and high local compressibility, belongs to complex soft rock of special type. On basis of the gypsum breccia geology of Z5 bid section of Taihangshan tunnel, the authors study on the geological background, origin and engineeringbehavior of gypsum breccia in the paper, placing the emphasis on the presentation of the results of the in-situ experiments on the engineering behavior of gypsum breccia.
