Comparing with the uniaxial compression, the Young's modulus and the yield stress of the biaxial compression increase obviously.
与单轴压缩相比较，双轴压缩的弹性模量和屈服应力有明显的提高。
Uniaxial compression tests are performed on saturated frozen sand at various temperatures and strain rates. The elastic modulus is obtained from these tests.
通过在不同温度及不同应变率下对饱和冻结中砂进行单轴压缩试验，获得了静载下饱和冻结中砂的弹性模量。
