【摘要】：安康地區(qū)位于陜西省東南部,市內(nèi)地形以山區(qū)為主,其特殊的地理環(huán)境以及氣候條件,導(dǎo)致安康地區(qū)公路水毀災(zāi)害十分嚴(yán)重。目前國內(nèi)常見的公路水毀治理方法主要是在水毀災(zāi)害發(fā)生后進(jìn)行治理,然而這類方法需要較大的投入,并且已發(fā)生的水毀災(zāi)害嚴(yán)重影響了公路的正常運(yùn)營以及車輛行駛安全。 本文以安康市境內(nèi)G210、S207和S310三條主要干線公路水毀治理工程為依托,進(jìn)行了大量的實(shí)地調(diào)研以及室內(nèi)資料的收集。對三條干線公路的水毀情況進(jìn)行了統(tǒng)計,并分析了水毀災(zāi)害產(chǎn)生的病因。在此基礎(chǔ)上,結(jié)合國內(nèi)現(xiàn)有的山區(qū)公路水毀文獻(xiàn),對安康地區(qū)公路水毀類型進(jìn)行了歸類總結(jié),確定了安康地區(qū)公路水毀典型類型,包括路基邊坡水毀、防護(hù)工程水毀、排水系統(tǒng)水毀和小橋涵水毀四個大類,每個大類又細(xì)分為不同的小類,從而將公路水毀類型明細(xì)化,為公路水毀的養(yǎng)護(hù)工作提供指導(dǎo)。 利用公路工程中常用的模糊綜合評價方法,對安康地區(qū)公路水毀路段的水毀風(fēng)險等級進(jìn)行評價。在此基礎(chǔ)上,針對水毀風(fēng)險等級為Ⅱ級或Ⅲ級的路段實(shí)施公路水毀預(yù)防性養(yǎng)護(hù)。進(jìn)而針對四個典型的公路水毀類型,提出了常規(guī)預(yù)防性養(yǎng)護(hù)措施和專項預(yù)防性養(yǎng)護(hù)措施以及綜合預(yù)防性養(yǎng)護(hù)措施,其中專項預(yù)防性養(yǎng)護(hù)包括路基邊坡水毀專項預(yù)防性養(yǎng)護(hù)、防護(hù)工程水毀專項預(yù)防性養(yǎng)護(hù)、排水系統(tǒng)水毀專項預(yù)防性養(yǎng)護(hù)和小橋涵水毀專項預(yù)防性養(yǎng)護(hù)四個大類。 最后結(jié)合公路水毀預(yù)防性養(yǎng)護(hù)工程實(shí)例,對公路水毀預(yù)防性養(yǎng)護(hù)的實(shí)施過程進(jìn)行了分析。并結(jié)合常規(guī)公路水毀養(yǎng)護(hù)措施,對比分析了公路水毀預(yù)防性養(yǎng)護(hù)效果,可以看出公路水毀預(yù)防性養(yǎng)護(hù)具有很大的經(jīng)濟(jì)性和可行性。
[Abstract]:Ankang region is located in the southeast of Shaanxi Province, the city is mainly mountainous terrain, its special geographical environment and climate conditions. Leading to serious road damage in Ankang area. At present, the common treatment methods of highway water damage in our country are mainly after the disaster of water destruction, but this kind of method needs more investment. And the damage disaster has seriously affected the normal operation of the highway and the safety of vehicles. This paper is based on three main trunk roads in Ankang City: G210S207 and S310. A large number of field research and indoor data collection, the three main highway water damage statistics, and analysis of the causes of the flood disaster. On this basis. Combined with the existing literature on highway water damage in the mountainous areas in China, the types of highway water damage in Ankang area are classified and summarized, and the typical types of highway water damage in Ankang area are determined, including subgrade slope water damage, protection engineering water damage. There are four types of water damage of drainage system and small bridge and culvert, each of which is subdivided into different subclasses, thus the types of highway water damage are classified into details, which provides guidance for the maintenance of highway water damage. Based on the fuzzy comprehensive evaluation method commonly used in highway engineering, this paper evaluates the risk grade of waterlogged road damage in Ankang area. The preventive maintenance of flood damage is carried out for sections with grade 鈪，
