摘要
通过青藏铁路涵洞试验工程的修筑和地温、变形、气温等相关项目的测试,经过对一个冻融循环过程观测数据以及针对试验工程中出现相关问题的综合分析,基本掌握了涵洞工程冻土问题的关键所在,提出了合理的建议和处理措施。
Based on the constructing of the Qinghai-Tibet Railway Experimental Culvert in permafrost region and the observation of ground temperature, distortion, air temperature and other relevant items. The data in one freezing-thawing circular are synthetically analyzed. Main problems in the experimental construction are also analyzed. Thus, the key problems of how to build culverts in the frozen soil regions are resolved, and some rational suggestions, as well as some disposal measures, are given.
