摘要
在对目前加筋土计算方法进行简要介绍的基础上,以河北某山区高速公路加筋路堤工程为研究对象,运用FLAC3D软件对加筋路堤的稳定性进行数值模拟分析和讨论.研究表明,现有的将筋土分开考虑的计算算法适用于加筋土的计算,且适用范围较广;将筋土作为整体复合材料考虑的计算算法由于假设偏离实际,且参数不易确定,不适合在工程设计中使用;等效附加应力法是一种新的加筋土计算理论,方法简单,是今后加筋土计算方法的研究方向.
After a brief introduction of the calculation methods of reinforced soil at present,the stability of reinforced embankment is analyzed by the FLAC 3D software for numerical simulation with a mountainous expressway reinforced embankment of Hebei province as the research object.The results obtained in this study show that the existing calculating algorithm on separately considering reinforced materials and soil are applicable to calculation of reinforced earth and can be applied widely.The calculation algorithm about reinforced soil composite as a whole is unsuitable when used in engineering design due to that the assumption deviates from the actual and the parameters are difficult to be determined.Equivalent additional stress method is a new and simple reinforced earth design theory,and is becoming much more active in the research of calculation method of reinforced earth.
