摘 要：
利用有限元程序,对小型钢加筋水泥土支护工程实例进行数值模拟计算。对基坑开挖后挡墙的受力特性,变形特性进行了有限元计算分析,通过计算,明确了组合挡墙受力后的变形情况以及水泥土和小型钢的工作状态、应力分布特点。证实在小变形下水泥土与型钢协同工作性能良好,对于深度不大的基坑支护工程,小型钢加筋水泥土组合支护结构非常适用。

摘 要：
Using the finite element procedure,simulation computation was performed to identify the parameters of the small scale reinforced cement soil support project.The retaining wall stress and the distortion features of the excavated structures were measured against the finite element computation analysis to identify the combined retaining wall distortion as well as the water soil and the small scale active status,and the stress distribution features.Satisfatory results were obtained regarding the small distortion cement soil and the section joint operation performance,suggesting that the reinforced cement soil support structure is suitable for the less deep excavations.
