摘要
本文以澳大利亚计算机应用协会(ACADS)的典型考题为基础,首先对该边坡在不考虑孔隙水压力情况下,采用FLAC程序进行了安全系数的求解,求解的结果和ACADS给出的参考答案非常接近,可见FLAC法的准确性。然后又分别对该边坡施加了不同的孔隙水压力,分别得到对应条件下的安全系数值,发现孔隙水压力对边坡的安全系数的大小是有影响的,但这种影响程度并不一样,当孔隙水压力在小于某个值时候,影响是非常小的,而孔隙水压力突破了这个值以后,孔隙水压力对边坡安全系数的影响就非常巨大。
On the basis of the Australian Computer Society（ ACADS）＇s typical questionsl （a） ,first, regardless of the slope in the case of pore water pressure, used FLAC procedure calculate the safety factor, the result was very close to the reference answer given by ACADS, we can see the accuracy of FLAC. Then, applied to the slope of different pore water pressure, obtained safety factor under corresponding conditions, then, we found that the pore water pressure had effect on the slope safety factor, but the influence are not same, when the pore water pressure less than a certain value, the influence are very small, but, when the pore water pressure exceeded this value, the influence became very large.
