土工格栅在软土地基的处理中具有质量可靠、施工便捷、工效高、工程成本低等特点,在道路建设中得到了广泛的应用和推广。本文结合襄樊市前进东路道路排水工程,着重介绍土工格栅在软土地基处理中的适用范围、作用、施工工序。软土是指以水下沉积的饱水的软弱黏性土或淤泥为主的土,有时也夹有少量的腐泥或泥炭层。在襄阳地区,大部分土层属于膨胀土。由于软基具有含水量大、压缩性高、承载能力低等特点,作为道路地基,处理不当时路堤易发生滑动 Geogrid in soft ground treatment with reliable quality, convenient construction, high efficiency, low cost and other characteristics of the road construction has been widely used and promoted. Combined with the drainage project of Qianjin East Road in Xiangfan City, this paper focuses on the application range, function and construction procedure of geogrid in soft soil foundation treatment. Soft soil refers to saturated, weakly clayey or silt-based soil that is submerged, sometimes with a small amount of sapropel or peat. In Xiangyang area, most of the soil belongs to expansive soil. As the soft foundation has the characteristics of large water content, high compressibility and low carrying capacity, as a road foundation, the embankment is prone to slip when handled improperly
