优化冻土地区路基结构设计提高道路使用性能

摘要

In road construction, in order to ensure the use function of the road and extend the service life of the road, great importance should be attached to the design of roadbed structure, especially for frozen earth area. Based on the survey and investigation of the actual situation of frozen earth area, this article points out the roadbed design principles in frozen earth area, and through using different design parameters in different sections, the roadbed damage degree under the same load is researched, which provides a reference basis for roadbed structure design in frozen earth area.%在道路施工中，为了确保道路的使用功能、延长道路的使用寿命，需要高度重视路基的设计结构，对于冻土地区来说更是如此。本文通过勘察、调查冻土地区的实际情况，指出冻土地区路基设计原则，同时通过对不同路段采用不同设计参数，研究相同荷载作用下路基破坏程度，用于指导冻土地区路基设计，为冻土地区路基结构设计提供参考依据。
