| 摘 要： | 通过对冻结钙质粘土的波速测定,证实随着温度的降低波速增大;波速与试件的密度有关,密度越大,则波速越大.并通过对不同低温下冻结钙质粘土的单轴抗压强度试验,得出其单轴抗压强度和弹性模量随温度的降低而增大.

| Abstract: | The measuring of wave velocity of frozen calcic clay shows:the wave velocity increases with temperature dropping;the wave velocity depends on density of test sample-the higher the sample density,the higher the wave velocity.The single-axis compression strength test of frozen clay under different low temperatures shows:the single-axis compression strength & elastic modulus of frozen clay increase with dropping of temperature. |
| |
| Keywords: | frozen calcic clay wave velocity single-axis compression strength |
