摘　　要：针对稻草加筋盐渍土进行试验,进行了最适宜加筋率和最适宜加筋长度的选择,得到最适宜加筋长度为15,mm,最适宜加筋率为0.20%.在土中添加长度为15,mm,质量加筋率为0.20%的稻草,研究了不同的筋材形状对加筋盐渍土和加筋石灰土的无侧限抗压强度的影响.An experiment with the saline soil reinforced with rice straw was done for the optimal choice of the rate and length of reinforcement,the result of which was 0.20% for the former and 15 mm for the latter.On the above condition,a research was carried out for the effects of different reinforcement shapes on the unconfined compressive strength of the rein-forced saline soil and calcareous soil.
