本研究探讨土工格室作为软土地基加筋之分析。为该应用提出的方程是基于先前开发的用于预测土工格室加固土壤的承载力的方法，该方法考虑了基础地层、土工格室填充土壤、土工格室垫的几何形状、边坡角和路堤荷载的特性。所提出的方法考虑了两种方法计算的未加固系统的安全系数，其中一项是依赖于土工格室钢筋被添加到获得的安全系数的加固系统。用两种不同的分析方法确定无加固体系的安全系数，通过算例说明了该方法的应用。由此得到的结果进行了比较，从一个三维有限元计算机分析的未加固和加固的情况下。
This study addressed the analysis of geocells as basal reinforcement for embankments on soft soils. The equation proposed for this application is based on a previously developed method for predicting the bearing capacity of geocell-reinforced soils, which considers the characteristics of the founding strata, geocell in-fill soil, geometry of the geocell mattress, the slope angle and load from the embankment. The proposed method considers the factor of safety of the unreinforced system calculated by two methods, to which a term that is dependent on the geocell reinforcement is added to obtain the factor of safety for the reinforced system. The application of the method is demonstrated by an example using two different analytical methods for determining the factor of safety of the unreinforced system. The results thus obtained were compared with those from a three-dimensional finite element computer analysis for both unreinforced and reinforced cases.
