Generally, slopes considered stable, hence there will be no landslides, and if landslide occurs, it will merely occurs on small blocks.Ĭopyright © 2018 Praise Worthy Prize - All rights reserved.īasahel, Hassan, and Hani Mitri. Referring to the rock mass classification results, it can be concluded that slopes location at Poboya with a good quality of rock mass is at schist of location 3. Schist at location 3 has values of 65-75 for RMR and 69-79 for SMR, and schist at location 4 have values of 56-70 for RMR and 59-85 for SMR. Meanwhile, for schist at location 2, the obtained values are 56-71 for RMR and 57-79 for SMR. The results showed that for gneiss at location 1, it obtained values of 60-69 for RMR and SMR as well. The classification of rock mass carried out through a field survey and a laboratory testing, and then determined according to methods of RMR and SMR. The research conducted at Poboya Gold Mine, it geographically located at central of Sulawesi province. The research is to determine rock mass classification and slope stability of metamorphic rocks. Miners conduct quarrying and slope slicing to extract gold ores every day, resulting in changes on slope stability. Calculations are made using finite element method using the software package ANSYS.Poboya Mountains is one of the gold mines located in Palu city. In the formulation of the problem of volume calculation is made eye fastening guys to span. Some fragments of the superstructure and the pylon designed as thin-walled space of local exposure to guys. The behavior of the span when wind impacts. They performed static calculations of cable-stayed span in linear and nonlinear formulations of the problem based on the sequence of mounting the stage of construction and operation. MIIT scientists carried out a large range of activities and checking calculations to evaluate the stress-strain state of the cable-stayed bridge span in the individual stages of installation and operation. Basic calculations and design of the bridge carried out “Giprotransmost”, but the design and construction of this unique artificial structures preceded research, which involved scientists Chairs “Bridges” and “Structural Mechanics”, Moscow State University of Railway Engineering (MIIT), and several other TsAGI organizations.
