Axialcompressiontest can use double knife-edge bearing to instead spherical hinge bearing;
轴心受压构件试验可采用双刀口支座代替球铰支座；

At present, four methods are mainly used for reinforcement earth research: prototype test, model test, three-axialcompressiontest, direct shear test and drawing test.
目前加筋土的试验研究主要有四种方法：原型试验、模型试验、三轴压缩试验、直剪试验和拉拔试验。

The objective function was defined as minimization between strains obtained from finite element method and ones observed from three-axialcompressiontest in laboratory.
