中文摘要：

试验性的节目在武汉沙岩上执行了的一个实验室在单音的补品装载下面被介绍，在装载与不同紧张的周期的装载评估在毛孔液体的不同条件和对他们的影响下面比较单轴的压缩力量和有弹性的性质(有弹性的模量和泊松比率) 的路径和正弦波浪期间的部分周期的装载。当装载紧张率是 10 ~ 时(-5), 10 ~(-4) 和 10 ~(-3)/s, 分别地，干燥沙岩的单轴的压缩力量是 82.3， 126.6 和 141.6 MPa，水的浸透沙岩分别地是 70.5， 108.3 和 124.1 MPa。上述结果证明然而，单轴的压缩力量随紧张率的增加增加弄软系数的变化是不足道的。在装载状况的单音的补品下面，正切模量在某个压力水平，它开始在以外衰退与应力(紧张) 的增长增加到最大的价值。在下面模量的在装载路径状况期间的部分周期的装载，卸掉或再装比装载模量，并且卸掉并且再装 moduli 大是关于压力水平的几乎常数，特别卸掉模量。在正弦波浪下面，周期的装载状况，正切模量和泊松比率显示不对称的“ X ”有各种各样的紧张的形状，和平均卸掉模量比平均装载模量大。

英文摘要：

A laboratory experimental program performed on Wuhan sandstones was presented under monotonic loading, partial cyclic loading during loading path and sine wave cyclic loading with different strain rates to compare uniaxial compression strength and elastic properties （elastic modulus and Poisson ratio） under different conditions and influence of pore fluid on them. When the loading strain rates are 10^-5, 10^-4 and 10^-3/s, uniaxial compression strengths of dry sandstones are 82.3, 126.6 and 141.6 MPa, respectively, and that of water saturated sandstones are 70.5, 108.3 and 124.1 MPa, respectively. The above results show that the uniaxial compression strength increases with the increase of strain rate, however, variation of softening coefficient is insignificant. Under monotonic loading condition, tangent modulus increases with an increment of stress （strain） to a maximum value at a certain stress level, beyond which it starts to decline. Under the partial cyclic loading during loading path condition, unloading or reloading modulus is larger than loading modulus, and unloading and reloading moduli are almost constants with respect to stress level, especially unloading modulus. Under the sine wave cyclic loading condition, tangent modulus and Poisson ratio display asymmetric ‘X＇ shape with various strain, and the average unloading modulus is larger than the average loading modulus.
