【摘要】：本論文針對濱海新區(qū)“重載、軟基、鹽漬化”特點(diǎn)，論文在理論研究及交通調(diào)查的基礎(chǔ)上，對集疏港重載交通的軸載換算方法、柔性基層路面結(jié)構(gòu)、結(jié)構(gòu)組合等進(jìn)行系統(tǒng)研究，提出一般交通條件下的瀝青路面典型結(jié)構(gòu)，超越規(guī)范要求的重載交通瀝青路面典型結(jié)構(gòu)，本論文的主要結(jié)論如下： 1、載重汽車中四軸1為集疏港交通的代表車型。集疏港重載交通軸載水平、輪壓標(biāo)準(zhǔn)、軸載次數(shù)均超越現(xiàn)有規(guī)范涉及的范疇，，需要從道路設(shè)計(jì)及交通管理采取措施應(yīng)對重載交通。提出單軸雙輪組大于130KN的軸載作為重軸載標(biāo)準(zhǔn)界限，為軸載換算的準(zhǔn)確性及判定是否考慮重載的影響提供方便。 2、推薦出濱海新區(qū)瀝青路面典型結(jié)構(gòu)以及重載瀝青路面典型結(jié)構(gòu)。 3、重載條件下路基加固處理形式及措施
[Abstract]:In view of the characteristics of "heavy load, soft foundation, salinization" in Binhai New area, this paper systematically studies the axle load conversion method, flexible base pavement structure, structure combination and so on, on the basis of theoretical research and traffic investigation, and makes a systematic research on the axle load conversion method, flexible base pavement structure and structure combination, etc. The typical structure of asphalt pavement under general traffic conditions and the typical structure of heavy-duty traffic asphalt pavement are proposed. The main conclusions of this paper are as follows: (1) 4-axis 1 is the representative type of traffic in gathering and distributing port. The level of axle load, the standard of wheel pressure and the number of axle load of heavy-duty traffic in the port are all beyond the scope of the existing codes. It is necessary to take measures to deal with the heavy-haul traffic from road design and traffic management. The axle load with single shaft and two wheels larger than 130KN is put forward as the standard limit of heavy axle load, which is convenient for the accuracy of axle load conversion and the determination of whether the influence of heavy load is taken into account. 2. The typical structure of asphalt pavement and heavy-duty asphalt pavement in Binhai New area are recommended. 3. Treatment forms and measures of roadbed reinforcement under heavy load conditions
