void-cement ratio

Study on Self-Adaptive Neural Network Identifying of Void on Rigid Pavement Based on Frequency Drawdown Ratio

基于频率下降率的刚性路面脱空自适应神经网络识别研究

The relations between initial tangential modulus, confining pressure, over-consolidation ratio and initial void ratio were deduced, and were proved through triaxial compression test.

建立了初始切线模量与围压、超固结比、初始孔隙比之间的关系式，并通过三轴试验进行验证。

It was different obviously between the critical macro-parameter of void divergence ratio VGC in the tensile abruption sample and those in the impact abruption sample ( diversity ratio up to the scale from 39% to 200%).

X80钢试样冲击断裂时的宏观形式的临界孔洞扩张比VGC与拉伸时的结果有很大的偏差（相差39%～200%）。

In the duration of deep bed filtration the void ratio of sediment will be varied with the average flow velocity gradient.

过滤过程滤层中沉积物的空隙率随水流平均速度梯度的改变而变化。

So the void ratio method is feasible in compaction control of subbase.

因此,路基压实用空隙率法控制是切实可行的.
