摘要:
高水巷旁充填材料在煤矿沿空留巷工程中得到了广泛应用,水灰比对其力学性质关系密切。首先通过扫描电镜分析了高水材料的微细观形貌,其次通过 RMT-301伺服试验机对1.3~2.5∶1等6种水灰比的高水材料试样进行了单轴压缩试验,得到了各水灰比试样的全应力-应变曲线,分析了试样的变形特征、强度及破坏特征、能耗特征随水灰比变化的规律。结果表明,高水材料的微观结构为固、液、气构成的多孔海绵状结构;高水材料的变形特征与岩样相似,也大致可分为压密阶段、线弹性阶段、屈服阶段以及峰后应变软化阶段,弹性模量、割线模量和峰值强度等随水灰比提高多呈指数函数关系下降;随着水灰比增大,试样由脆性破坏逐渐过渡到延性破坏;随着水灰比增大,试样吸收的总应变能与可释放弹性应变能均呈指数函数关系下降,而耗散能变化幅度不大。
Abstract:
The high-water roadside filling materials have been widely applied to the engineering of retaining roadways along goaf in coal mine, and its mechanical properties are closely related to the water cement ratio. Firstly, the micro morphology of the high-water material was analyzed by SEM. Then the uniaxial compression tests were conducted on the high-water material samples with six water cement ratios from 1.3∶1 to 2.5∶1 by the RMT-301 servo testing system. The full stress-strain curves of all the samples with different water cement ratios were obtained, and the variation laws of deformation characteristic, strength characteristic, failure characteristic, energy consumption characteristic with the water cement ratio were analyzed. The results showed that the microstructure of high-water material is a porous spongiform structure composed of solid, liquid and gas. The deformation characteristic of high-water material is similar to the rock samples, and it also can be divided into compaction phase, linear elastic phase, yield phase, and post-peak strain softening phase roughly. The elastic modulus, secant modulus and the peak strength decrease by exponential function with the increase of water cement ratio. The samples gradually transit from brittle failure to ductile failure with the increase of water cement ratio. The total strain energy and the released elastic strain energy absorbed by the samples both decrease by exponential function with the increase of water cement ratio, whereas the dissipation energy changes little.
