Analysis of engineering geology and stability of Malanwang Landslide
Landslide is the phenomenon that rock and soil mass of slope slips along the transfixed failure surface, which was destroyed by shear stress, with the reason that the shear stress in the sliding surfaces exceeds its shear strength. This paper takes Mayanwan Landslide for an example, used the Residual Thrust Force Method, the Janbu's Method and the Sarma's Method for stability calculation, based on interpreting the engineering geologic condition and natural environment of the research district and understanding the basic characteristics of the landslide, considering the rain and earthquake conditions.
DEVELOPMENT AND APPLICATION OF SOFTWARE SYSTEM FOR AUTOMATIC MONITORING ON GEOLOGICAL ENGINEERING
The functional construction, development tendency, and several key techhnical problems of software system for Automatic Monitoring on geological engineering are discussed in this paper. Studied these key problems and the characteristics ofdeformation and failure of geological engineering works, the authors developed a software system for automatic monitoring on large hydropower station slope works. Its powerful functions, special features and data analyzing, and prediction subsystem are introduced.
Limitations on the interpretation of biotite substitutions from chemical analyses of natural samples
Biotites, as well as other phases, are sufficiently complex chemically that there are numerous sets of linearly independent exchange components with which to describe the composition of a naturally occurring crystal. Even after complete chemical analysis, this leads to ambiguities in the correlation of exchange components with valid substitution mechanisms in complex phases. The best means of identifuing valid substitutions are by the observation of simple endmember compositions, the investigation of compositional changes in zoned crystals or petrogenetic sequences, and by direct experimental synthesis.
