Subsurface
structure and engineering properties of the Sivas and Erzincan railway route
were investigated by using velocities of seismic wave, electrical resistivity,
standard penetration test (SPT) data and laboratory results, which were
collected from survey sites referred to in this study. For this reason, 62
seismic refraction and vertical electrical resistivity (VES) measurements at 59
points were done along the survey route. Moreover, 11 mechanical boreholes with
SPT were drilled. Laboratory tests were applied on soil samples taken from
boreholes for geotechnical features. Longitudinal,
shear wave velocities and elastic parameters were determined by seismic refraction
method, and underground resistivity distribution was calculated by VES and
geotechnical data and SPT results were evulated for the subsurface integrity.
Engineering properties of a 6.8 km stretch of
planned railway alignment in southeastern Sivas were calculated in this study. According
to these results, unsuitable segments of the high-speed alignment which have
low groundwater level and low bearing capasities which depend on dynamic
properties were examined.
