All of the variational law of density, longitudinal wave velocity and tensile strength of gritstone after high temperature are studied.

对40块粗砂岩试件高温后的密度、纵波波速和抗拉强度变化规律进行了试验研究。

The results show that the density of gritstone is decreased gradually as the temperature increasing; so that it can be ignored; the longitudinal wave velocity is linearly decreased when the temperature increasing, and decrease rate of it follows the law of conic; R is one temperature point, which makes the law of tensile strength of gritstone after high temperature follows the law of parabola; and the maximal tensile strength appears when the operative temperature is R. After the temperature is higher than 700 ℃, tensile strength is small and change range is small when the temperature is increased.

结果表明，高温后粗砂岩的密度随试验温度的升高减小幅度很小，几乎可忽略不记；高温后试件中纵波波速的传播随温度升高基本呈线性降低，而减小率呈二次曲线规律变化；存在一个温度点R，使高温后试件的抗拉强度呈开口向下抛物线关系变化，且在R温度作用后试件抗拉强度达到最大；当试验温度大于700 ℃后，试件的抗拉强度变得很小，且当温度升高时变化幅度也很小。
