Abstract

Population growth and lack of space in some cities increased the need for public transportation and implementation of subway lines. One of the most important hazards in urban area tunneling is the possible effects of the SETTLEMENT on the surface structures. In this research, the effect of the main GEOTECHNICAL PARAMETERS on the surface SETTLEMENT has been studied. Literature show that simultaneous analysis of the parameters that affect tunnel behavior is not considered well. For this aim EXPERIMENTAL DESIGN can be used because of its ability to make changes in input variables (geotechnical parameters) and observe the output (SETTLEMENT) changes. On the other side use the expert knowledge in a ROCK ENGINEERING SYSTEM is useful in order to make judgment about complex systems. For this reason, this method was also applied in order to achieve research goal. A part of Karaj Metro tunnel Line was modeled by FLAC3D in order to use EXPERIMENTAL DESIGN. Compare the simulation results with monitoring data indicates the efficiency of numerical model in condition like this. Next, a range and sensitivity analysis was performed by using the Taguchi method. Results show that E and ν, respectively has the highest and the lowest impact on the surface SETTLEMENT. The output of the ROCK ENGINEERING SYSTEM is also show that E and ν, respectively has the highest and lowest interaction with other parameters of the interaction matrix.
