在我国东南部的机场建设中,场区往往会存在大面积的软土。软土具有高压缩性、低强度等特性,极易导致飞行区道面产生较大的不均匀沉降和边坡失稳,因此,机场飞行区的软土地基处理是机场建设过程中的关键。针对软土的工程特性,依据规范中对飞行区地基沉降、强度及边坡稳定性的要求,结合四个机场飞行区软土地基处理工程案例,着重从地基变形和强度方面展开分析,探讨了不同软土地基的处理效果,提出了飞行区软土地基处理建议。
In the construction of the airport in southeastern China, the area often has a large area of soft soil. Due to its characteristics of high compressibility and low strength, soft soil can easily lead to large uneven settlement and slope instability in the flight path. Therefore, the treatment of soft ground in the airport flight area is the key to the airport construction. According to the engineering requirements of the soft soil, according to the requirement of the settlement, strength and stability of the slope in the flight area, combining with the case of soft soil foundation treatment in the flight area of the four airports, the paper analyzes the deformation and strength of the foundation, Different soft soil foundation treatment effect, put forward the fly area soft soil foundation treatment suggestion.
