石粉垫层的研究与应用

本文介绍了石粉的形成和材料的特性， 对石粉垫层的力学特征作了研究， 取得了垫层的设计与施工参数。石粉垫层具有承载力高、压缩性低、应力扩散角大、自身消散附加应力能力强的特点。石粉垫层材料来源广泛、价格低廉、施工工艺简单， 是一种可推广应用的新型垫层材料。

Formation of powdery stone and its properties are introduced. Parameters for design and construction of cushion are acquired after investigated the mechanical characteristics of powdery stone cushion. The said cushion is equipped with high bearing capacity, low compressibility, large angle of stress dispersion. Sources of material for powdery stone cushion are widespread. With their low costs and simple construction process they are new cushion material to be popularized.
