By means of the experimental data from dynamic triaxial stress-strain test of variable cyclic amplitude for frozen soil, the formative conditions of residual strain on frozen silt clay are studied.
基于不等幅值循环荷载作用下低温三轴振动试验资料，研究了冻结粉质粘土在分级往返加荷情况下的残余应变产生条件。
Measuring the dynamic strain involves the constant modification of gain, as determined by the signal amplitude. This practice suffers from the complex test and the low accuracy.
在动态应变信号测试中，经常需要根据信号的幅值不断调整放大器的放大倍数，测量电路复杂，精度低。
