改良土无侧限抗压强度试件的制作方法对比

对改良土无侧限抗压强度试验的过程进行了介绍,着重对比了采用静压法、锤击法制件的无侧限抗压强度,不同尺寸试件的无侧限抗压强度。结果表明:采用锤击法制件得到的无侧限抗压强度平均值、偏差系数均大于采用静压法制件得到的无侧限抗压强度平均值、偏差系数。对于同一种土样,长柱试件无侧限抗压强度值与短柱无侧限抗压强度值有很好的线性相关性。

The preparation method contrast of improved soil unconfined compressive strength test pieces

This paper introduced the test process of improved soil unconfined compressive strength,emphatically contrasted the unconfined compressive strength using static pressure method,hammering method finished piece,unconfined compressive strength of different size test pieces.The results showed that: the unconfined compressive strength average value obtained by hammering method finished piece,the deviation coefficient was greater than the unconfined compressive strength average value obtained by the static pressure method.For the same soil sample,long column test pieces unconfined compressive strength value had good linear relationship to short column unconfined compressive strength value.
