【摘要】：在冻土地区修建公路,如何彻底治理多年冻土目前尚属世界性难题,世界各国都在积极寻找解决方案,但目前对于多年冻土还没有根治的方法,可供借鉴经验也不多,而且各地的冻土还有各自特点,对于别人的经验也不能全盘使用。尤其是农村公路,受投资限制,要想根治冻土病害的发生,难度很大。如在修建公路过程,对冻土不能妥善处理,建成后冻土病害将逐渐发生,将影响公路运营功能,严重的将影响行车安全。为了解决低投资的农村公路在修建过程中有效治理冻土,最大程度减少冻土病害发生,论文针对大兴安岭地区冻土现状及农村公路投资情况,对冻土路段修建的农村公路施工的关键技术进行了研究,找出了经济、合理、可行的方案,并得到了推广。论文通过总结以往修建公路冻土病害情况,在收集冻土相关资料并进行分析的基础上,对已完工程病害情况进行调查统计、病害分析,研究大兴安岭地区冻土病害产生的主要原因及主要处治方案;通过对不同处治方案效果、造价进行分析,在确保路面设计寿命周期内或大修期内不影响使用性能情况下,考虑农村公路建设投资情况,研究最佳方案;通过对具体工程进行实施及观测,最终确定方案可行性,确定适宜大兴安岭地区农村公路冻土处治的最佳方案。
[Abstract]:How to control permafrost thoroughly is still a worldwide problem in the construction of highway in permafrost regions. Countries all over the world are actively looking for solutions, but at present there is no radical cure for permafrost, and there are few experiences for reference. And the local frozen soil has its own characteristics, the experience of others can not be fully used. Especially the rural highway is restricted by investment, it is very difficult to cure the frozen soil disease. If the frozen soil can not be properly treated in the process of highway construction, the frozen soil disease will occur gradually after completion, which will affect the road operation function and seriously affect the safety of the traffic. In order to solve the problem of effectively controlling frozen soil and minimizing the occurrence of permafrost disease in the construction process of low-investment rural highway, this paper aims at the present situation of frozen soil in Daxing'anling region and the investment situation of rural highway. This paper studies the key technology of rural highway construction in frozen soil section, finds out the economic, reasonable and feasible scheme, and it is popularized. In this paper, through summing up the situation of the frozen soil diseases in the past, on the basis of collecting and analyzing the relevant data of frozen soil, the paper investigates and statistics the disease situation of the completed projects, and analyzes the diseases. This paper studies the main causes of permafrost diseases in Daxing'anling region and the main treatment schemes. By analyzing the effect and cost of different treatment schemes, it ensures that the pavement design life cycle or overhaul period will not affect the performance of the pavement. Considering the investment situation of rural highway construction, the best scheme is studied, and the feasibility of the scheme is finally determined through the implementation and observation of the concrete project, and the best scheme for the treatment of frozen soil of rural highway in Daxing'anling region is determined.
