2Determination of time-dependent strengths of salt pillars based on strain energy principle显示文摘The objective of this study is to determine the time-dependent strengths of salt mine pillars in the Maha Sarakham formation, northeast of Thailand. Strain rate-controlled triaxial compression tests have been performed on salt specimens under confining pressures from 0 MPa to 12 MPa. The strain rates are from 10^(-7) s^(-1) to 10^(-4) s^(-1). The axial stresses and lateral strains are monitored through the strain-softening region. The results indicate that the strengths and elastic moduli increase exponentially with the strain rates. The power creep law parameters are calibrated with the test results, and hence allows constructing series of strain-time curves for the salt pillars under different depths and extraction ratios. The strain energy density principle is applied to develop a strength criterion for the salt pillars. Combining this criterion with the series of the strain-time curves the time-dependent strengths of the salt pillars for different extraction ratios can be predicted.Prapasiri Junthong Supattra Khamrat Suratwadee Sartkaew Kittitep Fuenkajorn 2019International Journal of Mining Science and Technology2019,29,2:1

4软岩的长期耐久性试验研究显示文摘通过对13个岩样进行软岩崩解试验、点荷载试验和X射线衍射分析,分析出岩石耐久性和应力、矿物组成之间的关系。一种观点是从软岩崩解循环试验结果描述岩石退化特性。针对岩石耐久性引进一种新的分类体系,这种方法可以预测岩石当受到风化过程的影响下的应力。研究的目的是为了预测风化过程对出露于泰国东部的变质岩、沉积岩、火成岩三大岩类耐久性和应力的影响,此过程包括干燥和含水状态的模拟和加热和冷却的模拟,通过区域研究,将原位岩石的热吸收和实验室测量的岩石标本结果联系起来。Kittitep Fuenkajorn 文建军 2012四川建材2012,38,5:0
