摘要

为研究油页岩巷道围岩的流变特性

采用岩土SJ-1B三轴蠕变仪对油页岩进行了三轴蠕变试验。根据试验结果

建立了油页岩非线性蠕变方程。根据上述非线性蠕变方程

以吉林桦甸油页岩矿一井运输大巷为工程背景

分析了围岩的应力场和位移场

并对不同支护强度和应力状态下的蠕变变形进行了系统的分析。研究结果表明

油页岩蠕变具有非线性

控制油页岩巷道围岩过量变形的根本途径是改变围岩的应力状态

以及适当提高锚杆、锚索的初始预应力。本文为有效控制油页岩开采时巷道围岩的有害变形提供了理论依据。

Abstract

In order to study the rheological properties of oil shale surrounding rock of tunnel

the triaxial creep experiment of oil shale was carried out with SJ-1B triaxial creepmeter.Based on the experimental results

the nonlinear creep equation of oil shale was established.Taking mine shaft transportation tunnel of Huadian Oil Shale Mine in Jilin Province as an engineering background

this paper analyzes the stress field and displacement field of the surrounding rock of tunnel

and systematically discusses the creep deformation under different support intensities and stress states.The research results show that the creep of oil shale indicates nonlinearity and the fundamental way to control excessive deformation of surrounding rock of tunnel is to change the stress state of rock

appropriately increase the initial prestress of anchor rod and anchor rope.The method presented in this paper provides a theoretical basis for effectively controlling harmful deformation of surrounding rock of tunnel in oil shale mining.
