与沿海地区的软土相比,兵团垦区的沼泽软土在地质状况、公路等级、交通量和工程造价控制等方面均有很大差异,因此,对内陆沼泽软土地基的处理方式不能沿用沿海的软基处理措施。国内外针对内陆沼泽软基的处理技术的研究不多。因此,针对兵团垦区沼泽软土的特点,寻求适合垦区沼泽软土公路修筑的路基处治技术对于兵团的公路建设具有积极的意义。本文在充分收集、消化、吸收国内外关于沼泽软土地区筑路技术研究成果的基础上,结合兵团的公路建设计划,对农四师吐坡公路进行了现场试验研究,总结提出了沼泽软土地区路基在填筑期间及运营期间的沉降规律。
Compared with the soft soil in the coastal areas, the swamp soft soil in the Corps reclamation area has great differences in terms of geological conditions, road grades, traffic volume and project cost control. Therefore, the handling methods of the inland swamp soft soil foundation can not be used Soft foundation treatment measures along the coast. Domestic and foreign research on the processing technology of inland swamp soft base is not much. Therefore, in view of the characteristics of swamp soft soil in XPCC Reclamation Area, it is of great significance to find a suitable subgrade treatment technology for swamp soft soil highway construction in Xiblao Reclamation Area for highway construction of XPCC. On the basis of fully collecting, digesting and assimilating the domestic and foreign research results of the road construction technology in swampy soft soil areas, this paper combines the Corps highway construction plan, Settlement regularity of subgrade in area during filling and during operation.
