Deformation Mechanism and Stability of a Rocky Slope

A high slope is located on the side of the spillway at a hydropower station in Southwest China, which has some weak inter-layers inclining outwards. Parts of the slope show heavy weathering and unloading. There appeared deformation and tensile crack either on the surface or on the afteredge of the slope during excavation, and under a platform （elev. 488 m）, two levels of slopes collapsed on the downriver side. Based on the investigation in situ and the analysis of the geological structure, the conceptual model of deformation and failure mechanism was erected for this slope. Furthermore, the deformation characteristics were studied with FLAC^3D numerical simulation. Comprehensive analysis shows that the whole deformation of the slope is unloading rebound in certain depth scope and the whole body does not slide along any weak interlayer. In addition, two parts with prominent local deformation in the shallow layer of the slope show the models of ＂creep sfiding-tensile cracking＂ and ＂slidlng-tensile cracking＂, respectively. Based on the above analysis, the corresponding project of support and reinforcement is proposed to make the slope more stable.     

锦屏花桥金矿床地质特征

过去认为远景不大的花桥金矿床,目前开采情况是可观的,与原评价结论相差较大,本文在前人工作的基础上结合开采揭露的地质现象较全面对对矿床的地质特征进行探讨,特别对新发现的Ｆｘ剪切破碎带进行了详细研究,认为它对矿床具有重要的控制作用,对该区寻找新的富矿体和同类型金矿均具有重要意义。     

用KX射线分析地质样品中的铀

应用半导体探测器和放射性同位素激发的 X 射线荧光法分析了地质样品中痕量铀。~(57)Co 激发源制成峰与本底比率高的形式。取10分钟测量时间,用强度为0.26×10~9贝克勒尔(0.26GB_q)的激发源,方法的检测限为24微克/克,源的强度增强10倍,检测限可提高到9微克/克左右。对于锡、铈、钨和钍的检测限亦作了测定。
