| 摘 要： | 对红山窑水利枢纽工程中的风化红砂岩进行膨胀特性试验研究.试验表明,不同风化程度的红砂岩随着含水率的逐渐加大、风化程度的加深,其自由膨胀率、有侧限自由膨胀率和膨胀力都逐渐增大,其中,强风化砂岩的膨胀率与膨胀力随含水率的变化而改变的幅度最大,并与上部荷载的大小密切相关.

| Abstract: | The expansive properties of the weathered red sandstone in Hongshanyao Hydro Project are studied by experiments.Some conclusions are drawn: with the increase of water content and degree of rock weathering,the free expansion ratio with or without lateral restraint and the expansive stress of sandstone gradually increase;the variations of expansion ratio and expansive stress of seriously weathered sandstone due to the change of water content are most significant,and they are closely related to the upper loads. |

| Keywords: | red sandstone expansive properties water content degree of weathering |
