新疆地区公路软土路基处理施工工艺研究

由于新疆地区主要由山脉和盆地组成，造成道路建设施工难度大，尤其是在复杂环境下的软土路基处理比较困难。“粉体喷射搅拌桩＋超载预压”处理软土路基的施工工艺具有路基沉降量较小、土体抗剪承载力加大、处理后的复合地基能够承载较大荷载等优点，对新疆地区复杂地段软土地基处理提供了借鉴。

Construction Technology of Handle Highway Soft Soil Subgrade in Xinjiang Region

The complex terrain mainly composed of mountains and basins in Xinjiang causes the road construction works to be difficulty, especially soft soil treatment with the complex environment is more difficulty. Construction technology of treating soft soil roadbed ＂powder guniting and mixing piles and surcharge preloading＂ has some advantages such as less roadbed settlement, increasing soil body shear strength and treated soft soil roadbed withstanding larger loads, which can provide references for soft soil roadbed treatment in the Xinjiang region complicated section.
