摘　　要：本文将具有各种不良工程特性并极易引发工程事故的岩石和岩体称为"劣质岩"(问题岩)"。文中分别论述了极软岩、膨胀岩、构造岩、片状变质岩、含盐岩、疏松岩、风化岩等常见劣质岩(问题岩)的成因和工程特性,以引起工程界的注意和进一步研究。The rocks and rock masses which have bad engineering characteristics and easily result in accidents are called the bad rocks or problem rocks. The genesis and the engineering characteristics rocks such as soft rocks, swelling rocks, tectonites, flaked metamorphic rocks, salt- bearing rocks, engineering of the bad loose rocks and weathered rocks are expounded respectively, which should be paid attention to by engineers and further studied.
