Evaluation of engineering properties of rock properties encountered in the tunnel of 35 in Ankara-İstanbul high speed railway project

SUMMARY High speed train Project between İstanbul-Ankara, contains double_track railway construction which is total 533 km long. After complaning Ankara-İstanbul will be three hours. This Project consists of ten section Tunnel 35 which, found on line Vezirhan-İnönü 54 km. The total length of tunnel is 3254,99 meters was opened by the New Austrian Tunneling Method (NATM). In this study some test results obtained from Tunnel 35, the rock quality indicator (RQD), uniaxial compression(σc), rock mass classification system (RMR), rock tunneling index (Q), daily progress, the amount of excavation and convergence were examined by different regression model. In this direction changing of those correspending the values of the independent veriables, the value of the dependent variable was examined by Linear, Logaritmic, Inverse, Quadratic, Cubic, Power, Compound, S, Growth and Exponential models. The main purpose of the study constitute the regression analysis in 5th and 6th sections. In 5th section regression analysis, dependent variable; was predicted by using the amount of excavation(KM), independent variable; RQD, σc, RMR, Q and daily progress. The best analysis is rock tunneling index(Q) and the best model is Cubic Regresyon model. As aresult of that in Cubic Regresyon model R2 =0,738, F =172,503 and determine model KM=142,960+706,422Q - 2241,383 Q2 + 2642,337 Q3 were determined. In the 6th section dependent variable maxsimum convergence and the ultımate convergence, there is no change for independent variable. In this section correlating Rock Tunneling Index (Q) is designed to provide the most suitable models was found to be Compound, Growth and Exponential Regresyon models R2 =0,415, F =128,265 and determine models MK=36,215*0,002Q, MK=e(3,589-6,142Q) and MK=36,215*e-6,142 were determined.
