前言所有岩体,特别是软弱岩体,在一定载荷的长期作用下,都具有变形随时间增长而影响其强度的流变特性.这一点,早被许多学者的研究结果及岩体工程实践所证实. 众所周知,断层破碎带、软弱夹层以及被松软物质充填的各种结构面(以下统称弱层)的流变性质更为显著.弱层是许多工程基岩或围岩经常碰到的.因此,对弱层流变特性及其对强度的时间效应的研究,从理论和实践上都有重要的意义.
Foreword All rock masses, especially soft rock masses, have long-term effect of a certain load, all have the rheological characteristics that deformation increases with time and affect its strength. This has long been the result of many scholars’ research and rock mass engineering practice. It is well known that the rheological properties of the fault crushing zone, weak intercalation zone, and various structural planes filled with loose materials (hereinafter collectively referred to as weak zones) are more pronounced. The weak zone is often encountered by many engineering bedrocks or wall rocks. The study of the rheological properties of the weak layer and its time effect on the strength has important implications both theoretically and practically.
