北方冬季漫长,大部分土层会形成施工困难的冻土层,尤其是高寒地区,比如青藏、东北等地区,这也就意味着对冻土地区的道桥施工技术的要求也相对较高。这几年科技的进步不断取得了优异的成果,对冻土层的施工技术也有了一定的研究。就冻土道桥的施工现状、施工要点和特点以及具体措施进行详细解析,旨在为我国冻土施工的技术的改进和提高提出一些有价值的参考意见。
The long winter in the north, most of the soil will form the permafrost in construction difficulties, especially in the alpine regions such as Qinghai-Tibet and northeast China, which means that the requirements for the bridge construction technology in the permafrost region are also relatively high. In recent years, the progress of science and technology has made excellent achievements, and has also done some research on the construction technology of permafrost. The construction status of the frozen soil bridge, the construction of the main points and characteristics as well as detailed analysis of specific measures designed to improve and improve the technology of frozen soil construction in our country put forward some valuable suggestions.
