【摘要】：从20世纪80年代以来,水毁损失是逐年上升。随着中国高速公路建设已大规模延伸到山区,山区高速公路也成了排水设施毁坏的重灾区。有必要对山区高速公路路基排水设施开展研究。首先,本文收集查阅吉林、浙江、江西、四川、云南五个省份的几条高速公路的部分山区路段的路基排水设施破坏资料,并对江西进行了实地调查。在进一步分析进一步完善的基础上,对其排水沟、边沟、急流槽和截水沟等路基的排水设施及其相关的破坏型式和原因进行了分析。其次,对山区急流槽与边沟的设计方法与施工工艺的相关问题展开了研究。针对发现的山区高速公路路基排水设施破坏的类型,进一步提出了适合于山区高速公路路基排水的两种新型式即:塑料管急流槽、生态型植草沟。最后运用模糊评价法进行了急流槽材料方案优选,并从排水设施的排水功能与自身稳定性的角度出发,对PVC管急流槽的合理性进行了研究。提出了PVC管急流槽的合理性评价体系,运用模糊综合评价的方法对PVC管急流槽的合理性进行了评价,结果证明该体系可信,具有一定的可行性。
[Abstract]:Since the 1980 s, the loss of water damage has increased year by year. As highway construction in China has extended to mountainous areas, mountain highways have also become a major disaster area for the destruction of drainage facilities. It is necessary to study the drainage facilities of highway roadbed in mountainous area. Firstly, this paper collected and consulted the damage data of subgrade drainage facilities in some mountain sections of several highways in Jilin, Zhejiang, Jiangxi, Sichuan and Yunnan provinces, and carried out a field investigation on Jiangxi Province. On the basis of further analysis and improvement, the drainage facilities of the subgrade, such as drainage ditch, edge ditch, jet channel and intercepting ditch, are analyzed as well as the relevant failure types and causes. Secondly, the design method and construction technology of jet channel and side ditch in mountainous area are studied. In view of the type of damage to roadbed drainage facilities found in mountainous areas, two new types of subgrade drainage suitable for mountain expressway subgrade drainage are put forward, that is, plastic pipe jet channel and ecological planting grass trench. At last, the method of fuzzy evaluation is used to optimize the material scheme of the jet trough, and the rationality of the jet trough of PVC pipe is studied from the point of view of drainage function and stability of drainage facilities. The rationality evaluation system of PVC pipe jet trough is put forward. The rationality of PVC pipe jet trough is evaluated by fuzzy comprehensive evaluation method. The results show that the system is credible and feasible.
