Abstract

Research purposes: In combination with the survey and design of Yumeng railway, a comparison and research have been performed of engineering geological condition of various proposals for major bridge site and route selection in the gorge section with the complicated geological condition in the mountain area to determine the reasonable proposal of bridge site and route.
Research methods: Following the principle of" the route submitting to bridge site and the bridge site submitting to the geology for choice", the paper adopts the integrated prospecting methods for geology and discloses in detail the major engineering geological problems in the gorge area.
Research results: Through systematically researching geology and summing up the experience of route selection in geology of this project route selection, the author proposed the principle of "The site selection for the major project must be adhered to and the in macro areal geology must be attached importance to under the condition of complicated geological environment" and the issues must be paid attention to in survey and design. Finally, the proposal of bridge site and route with better engineering geological condition was determined.
Research conclusions: As the Qujiang gorge section for the Yumeng railway passing lies in the highly-intensive seismic area, active fault zone nearby and the internal and external dynamic geological disaster is quite remarkable. So it is difficult to choose the site of Qujiang Major bridge-major control work. Nevertheless, the engineering technicians have committed themselves to perform a comparison and research of the local geologic environment and principal engineering geologic problems of 8 bridge sites and 4 route proposals. Finally they determine the C2K route proposal of 5# the bridge site and create the favorable condition for design and construction of project.
