【摘要】：本文研究的小草湖-吐魯番段高速公路《國(guó)家高速公路網(wǎng)規(guī)劃》“五縱七橫”的國(guó)道主干線連云港至霍爾果斯高速公路(G30)的組成部分;是新疆交通運(yùn)輸規(guī)劃57712高速、高等級(jí)公路網(wǎng)橫一的組成部分;同時(shí)也是G30連-霍與G7京-新兩條戰(zhàn)略地位重要的國(guó)道主干線共線段;已被列入“十二五”高速公路建設(shè)規(guī)劃之中。連接了阿勒泰市、北屯鎮(zhèn)和福�？h,是該路段內(nèi)南北向聯(lián)系的干線公路。本文的主要研究?jī)?nèi)容包括路線設(shè)計(jì)選定,借鑒國(guó)內(nèi)已研究出來的特殊路基處理經(jīng)驗(yàn)和辦法,結(jié)合本文研究的具體路段的沿線地質(zhì)、地貌、水文、氣象等因素,闡述了鹽漬土的危害,并就特殊路基的處理,得出以下結(jié)論:(1)該路段穿越區(qū)域自然環(huán)境較為復(fù)雜,充分考慮人、車、路的關(guān)系、建設(shè)與環(huán)境等各類關(guān)系,滿足交通的需求。對(duì)比本文提出的推薦路線和比較路線優(yōu)缺點(diǎn)后得出:比較方案雖然能夠更多的利用G312線,且有利于吐魯番市的居民能夠更加快捷的上下高速公路,但缺點(diǎn)也較為明顯,且費(fèi)用較推薦方案高出很多,所以課題組建議采用推薦方案。(2)路段區(qū)域內(nèi)干旱少雨,夏季高溫,蒸發(fā)量大于降水量的幾十倍,使得土中可溶性鹽隨著毛細(xì)水上升聚于表層,形成特殊地段,根據(jù)種類進(jìn)行科學(xué)劃分歸類,通過實(shí)驗(yàn)測(cè)得該路段區(qū)域干土內(nèi)的含鹽量大小,最終按照鹽漬土路段特殊路基進(jìn)行處理。(3)經(jīng)過比對(duì)和借鑒國(guó)內(nèi)經(jīng)驗(yàn),結(jié)合實(shí)地土中的含鹽性質(zhì)、含鹽量的不同,路基挖填及老路利用情況,主要選擇采用礫石土換填、土工布隔斷、降低路基水位三種方法進(jìn)行鹽漬路段的特殊路基處理。
[Abstract]:The national highway network planning of Xiaocaohu-Turpan section studied in this paper is a part of Lianyungang to Horgoz Expressway G30, which is the main line of "five columns and seven transverse". It is the 57712 expressway of Xinjiang Traffic and Transportation Planning. The high grade highway network is a part of the first section of the highway network, and it is also a common section of the main national highway between G30 Lian-Huo and G7 Beijing-New strategic position, and has been included in the "12th Five-Year Plan" highway construction plan. Connecting Altay City, Beitun Town and Fuhai County, it is the trunk road with north-south connection. The main research contents of this paper include route design and selection, reference to the experiences and methods of special roadbed treatment that have been studied in China, combined with geological, geomorphological, hydrological and meteorological factors along the specific road sections studied in this paper. The harms of salinized soil are expounded, and the following conclusions are drawn on the treatment of special subgrade. The following conclusions are drawn: (1) the natural environment of this section is more complicated, and the relationships among people, cars, roads, construction and environment are fully considered to meet the needs of traffic. After comparing the advantages and disadvantages of the recommended route and the comparative route proposed in this paper, it is concluded that although the comparison scheme can make more use of the G312 line, and is beneficial to the residents of Turpan City to be able to move up and down the expressway more quickly, the disadvantages are also obvious. And the cost is much higher than that of the recommended scheme. Therefore, the research group suggested that the recommended scheme should be used in the area with less drought and less rain, high temperature in summer and evaporation more than tens of times of the precipitation, so that the soluble salt in the soil accumulated in the surface layer with the increase of capillary water. Forming a special section, scientifically classifying and classifying it according to the type, measuring the salt content in the dry soil of the section by experiment, and finally treating the special subgrade of the section of saline soil according to the special roadbed of the section of saline soil, after comparing and drawing lessons from the domestic experience, Combined with the salt property of soil, the difference of salt content, the subgrade digging and filling and the utilization of the old road, three methods, gravel soil for filling, geotextile partition and lowering the subgrade water level, are mainly adopted to deal with the special subgrade in the salinized section.
