强风化岩开采料的细料含量很低 ,能否用作高土石坝防渗土料 ,取决于其在压实过程中的颗粒破碎程度。本文对取自同一料场的两种强风化砂页岩料进行了大量的击实试验研究 ,分析了不同条件下土料的压实特性和颗粒破碎规律 ;通过不同控制条件下土料的渗透试验 ,探讨了多种影响因素对土料渗透性能的影响规律 ,提出了强风化岩作为防渗土料使用的建议措施。 The content of fine material in the strong weathering rock mining material is very low, so it can be used as a seepage control material for high embankment dam, depending on the degree of particle breakage during compaction. In this paper, a large number of compaction tests were conducted on two kinds of strongly weathered sand shale materials from the same field. The compaction characteristics and particle breaking rules of the soil under different conditions were analyzed. Through different control conditions, The influence of many influencing factors on the permeability of soil material was discussed, and the recommended measures for using it as anti-seepage soil material were put forward.
