摘　　要：采用一种国产生物蛋白酶和熟石膏粉作为外掺料,对黑色泥炭质水泥加固土进行了不同配比条件下3个龄期的加固土室内无侧限抗压强度的正交试验研究,对试验结果进行了方差和显著性分析,还进行了试块在硫酸钠溶液中浸泡的试验,验证了熟石膏粉和该种蛋白酶具有提高泥炭质水泥土试块强度的效果,试块具有一定的抗硫酸盐侵蚀的能力。By adoptting protease that is a kind of enzymes which is homemade and hemihydrate gypsum as additives, for black peaty soil solidified with the cement , made a process of experimental study on unconfined compression strength tests which is orthogonal designed by different age of different mixed ratio of solidified soil. Analysed the result of variance and markedness of the experiment. In addition, texted the resist of sulphate of the solidified soil. It validated this protease, and gypsum have effect to inhance the strength of peaty solidified soil with the cement, and it has a definite ability to resist sulphate.

关 键 词：泥炭质土 加固 蛋白酶 无侧限抗压强度 正交设计试验
