【摘要】：從20世紀80年代以來,水毀損失是逐年上升。隨著中國高速公路建設已大規(guī)模延伸到山區(qū),山區(qū)高速公路也成了排水設施毀壞的重災區(qū)。有必要對山區(qū)高速公路路基排水設施開展研究。首先,本文收集查閱吉林、浙江、江西、四川、云南五個省份的幾條高速公路的部分山區(qū)路段的路基排水設施破壞資料,并對江西進行了實地調(diào)查。在進一步分析進一步完善的基礎上,對其排水溝、邊溝、急流槽和截水溝等路基的排水設施及其相關的破壞型式和原因進行了分析。其次,對山區(qū)急流槽與邊溝的設計方法與施工工藝的相關問題展開了研究。針對發(fā)現(xiàn)的山區(qū)高速公路路基排水設施破壞的類型,進一步提出了適合于山區(qū)高速公路路基排水的兩種新型式即:塑料管急流槽、生態(tài)型植草溝。最后運用模糊評價法進行了急流槽材料方案優(yōu)選,并從排水設施的排水功能與自身穩(wěn)定性的角度出發(fā),對PVC管急流槽的合理性進行了研究。提出了PVC管急流槽的合理性評價體系,運用模糊綜合評價的方法對PVC管急流槽的合理性進行了評價,結(jié)果證明該體系可信,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.
