Abstract Abstract:Research purposes: Heshun-Xingtai railway passed through Taihang mountains,nearby Luluo railway station,there is steep terrain,for the canyon walls,collapse,rockfall and other bad geology have development, groundwater is rich, geological conditions is complex. It is the basis of Luluo railway station about outside and tunnel type selection to find out the formation lithology,geological structure,the distribution range and development degree of collapse and rockfall. In order to make the thorough investigation of the engineering geological and hydrogeological conditions,comprehensive investigations were applied,and combined with the national scenic area and Xingfen highway slope stability condition, this paper put forward opinions on the line selection reasonable geological Luluo railway station. Research conclusions: (1)The outside Luluo station avoids collapse and rockfall development area, it is a good engineering geological conditions, and the engineering investment is less. (2) The outside station is safe and convenient about construction and operation scheme. (3) The outside station tunnel construction scheme near the expressway by using small dosage controlled blasting and TBM small tunnel construction measure, can avoid rockfall induced near the highway slope. (4)The outside Luluo station scheme is better than full tunnel scheme,it is recommended.(5)This paper can provide reference and guidance for the geological selection in the complicated terrain and the development area of collapse rockfall.
