【摘要】：從20世紀(jì)80年代以來(lái),水毀損失是逐年上升。隨著中國(guó)高速公路建設(shè)已大規(guī)模延伸到山區(qū),山區(qū)高速公路也成了排水設(shè)施毀壞的重災(zāi)區(qū)。有必要對(duì)山區(qū)高速公路路基排水設(shè)施開(kāi)展研究。首先,本文收集查閱吉林、浙江、江西、四川、云南五個(gè)省份的幾條高速公路的部分山區(qū)路段的路基排水設(shè)施破壞資料,并對(duì)江西進(jìn)行了實(shí)地調(diào)查。在進(jìn)一步分析進(jìn)一步完善的基礎(chǔ)上,對(duì)其排水溝、邊溝、急流槽和截水溝等路基的排水設(shè)施及其相關(guān)的破壞型式和原因進(jìn)行了分析。其次,對(duì)山區(qū)急流槽與邊溝的設(shè)計(jì)方法與施工工藝的相關(guān)問(wèn)題展開(kāi)了研究。針對(duì)發(fā)現(xiàn)的山區(qū)高速公路路基排水設(shè)施破壞的類(lèi)型,進(jìn)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(yùn)用模糊評(píng)價(jià)法進(jìn)行了急流槽材料方案優(yōu)選,并從排水設(shè)施的排水功能與自身穩(wěn)定性的角度出發(fā),對(duì)PVC管急流槽的合理性進(jìn)行了研究。提出了PVC管急流槽的合理性評(píng)價(jià)體系,運(yùn)用模糊綜合評(píng)價(jià)的方法對(duì)PVC管急流槽的合理性進(jìn)行了評(píng)價(jià),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.
