Electromagnetic testing and ultrasonic testing are the main points for materials hardness, hardness depth, crystallite size, limiting intensity etc.
对材料硬度、硬化层深度、晶粒大小、极限强度等主要采用电磁检测和超声检测。
The limiting equilibrium method that determines the influence depth of the expansive soils by the air is presented.
提出了确定膨胀土大气影响深度的极限平衡法;
Large scale numeric calculation shows that the active limiting displacement is increasing with the depth of retained soil, and that the increment is zero when the soil depth reach some degree.
大量数值计算表明:主动极限位移随土层深度增加而增加,但到一定深度后其增量为零。
