摘要

直接针对目前多年冻土场地道路工程抗震问题研究尚很薄弱这一事实,以在建的青藏铁路工程的抗震设计与地震加固为应用背景,基于若干种较为典型的多年冻土场地路基工况,开展多年冻土场地路基地震动位移性状的研究工作。研究表明,与不同的场地地形条件相比,场地冻土层厚度对路基地震位移响应的影响更加突出,尤其是含冻土融层路基的地震动位移值较不含冻土融层路基的地震动位移值大,因而冻土融层的存在无疑加剧了多年冻土场地路基的震害响应。
A present study of earthquake resistance of road engineering aseismic on permafrost site is still weak, and based on several typical roadbed cases on the permafrost site, seismic displacement property of roadbed on permafrost site is studied on a background of the seismic design and earthquake strengthening of Qinghai-Tibet Railway engineering. It indicates that the thickness of frozen soil layer has great influence on seismic displacement of roadbed comparing to the different terrains, especially the seismic displacement values of roadbed with thawed soil are larger than that without thawed soil. So the exist of thawed layer increases earthquake damage response of the roadbed.
