加筋土的研究工作至今多以小比例尺模型进行。这对确定实验室用土与现场用土之间不同颗粒级配的影响、边摩阻的影响,以及在精确标定重力应力上比较困难。所以它仅能提供模型原体实际特性的近似值。解决这一困难的合理途径是在现场建造大比例尺模型并研究其在破坏时的性能。对设计利用现场试验资料的方法作为这次研究的基础。
Reinforced soil research so far more than a small scale model. This has the effect of determining the effect of different particle gradations between lab soil and field soil, the influence of edge friction, and the precise calibration of gravity stress. So it only provides an approximation of the actual characteristics of the prototype protoplasts. A reasonable way to solve this difficulty is to build a large-scale model in the field and study its performance in the event of damage. The method of using field test data was designed as the basis of this study.
