摘　　要：通过一系列无侧限抗压强度试验,研究了硫酸盐环境中含盐量和浸水条件对2∶8灰土强度的影响规律。试验结果表明:无侧限条件下,2∶8灰土属于脆断性材料,其脆断性受浸水条件和含盐量影响,浸水后2∶8灰土脆断现象减弱,且含盐量越大2∶8灰土脆断现象越不明显。硫酸盐环境中,2∶8灰土水稳定性较差,浸水后2∶8灰土强度随着环境中含盐量的增大而减小,且二者呈线性关系。A series of unconfined compressive strength test was done for the research of the law of influence of salt content and submerging conditions in sulfate environments on 2 ： 8 lime-soil strength. The test result shows that, under the unconfined condition,2 ： 8 lime-soil belongs to brittle failure material and its brittle failure is affected by the salt content and submerging conditions. After submerging, brittle failure of 2 ： 8 lime-soil weakens and the larger the salt content is,the less evidence the brittle failure of 2 ： 8 lime-soil will be. In sulfate environments,2 ： 8 lime-soil has low stability and after submerged in the water,its strength will decrease with the increase of salt content and both presenting linear relationship.
