摘要/Abstract

摘要： 崩解性是膨胀岩最基本的特性之一，但在膨胀岩膨胀性的快速判别指标中少见关于崩解性及崩解物的定量指标。因此，有必要开展膨胀岩崩解物粒径分布特征和崩解性与膨胀性之间关系的研究，以对膨胀岩的快速判别进行补充。以浙江台州黑洞、蛇蟠岛和新疆大阪隧洞泥质岩样品为例，进行了干燥饱和吸水率和干燥饱和崩解试验，并分析了干燥崩解物粒径分布特征、耐崩解性指数及其与基于干燥饱和吸水率的膨胀性判别结果之间的关系。结果表明，膨胀岩膨胀性的强弱与其崩解物的最大含量粒组颗粒粒径、有效粒径和耐崩解性指数呈反相关关系。膨胀岩崩解物粒径分布的差异性对其膨胀性具有一定的指示意义。

Abstract: Slaking is one of the most basic characteristics of swelling rocks. However, criteria refer to slaking and characteristics of collapsed scraps are rare among rapid identification and classification criteria available. Thus, it is necessary to explore into slaking and grain size distribution (GSD) of the dry collapsed scraps of swelling rock and their relationships with the level of expansibility, which can complete the rapid identification and classification criteria with respect to slaking. With argillaceous rock samples collected from Daban Tunnel in Xinjiang Uygur Autonomous Region, and Heidong Cavern of Taizhou and Shepan Island in Zhejiang province, laboratory tests of saturated water absorptivity of dry rock block and slaking test are conducted; and GSD of the dry collapsed scraps, slake durability index and their relationship with expansibility derived from saturated water absorptivity of the swelling rock are analyzed. Results show that the effective grain size, grain sizes of the particle group with the maximum content and slake durability index are inversely correlated with the level of expansibility of the swelling rock. It is concluded that GSD of dry collapsed scraps of swelling rock can approximately act as an indicator for the level of expansibility.

Key words: swelling rock, expansibility, slaking, grain size distribution, inverse correlation
