复合固结土力学性能试验研究

对掺有ZL-1，EN-1和ISS土质固化剂的固结土进行无侧限抗压强度试验，结果表明ZL-1固化剂的固化效果较好。通过对不同胶结材料的复合固结土的室内试验，得到复合固结土的强度与配合比、期龄、固化剂的掺量、压实度之间的关系，并得到混合料的最佳强度配合比为1∶200～1∶400。

Experimental Study on Mechanical Properties of Compound Consolidated Soil

Taking consolidated soil respectively mixed with ZL-1, EN-1 or ISS soil solidifying agents, unconfined compression tests were carried out. As a result, it is obtained that the solidifying effect of ZL-1 agent is of the optimum. Through the indoor tests in relation to the compound consolidated soil that is mixed with different cementitious materials, the relation between the strength of compound consolidated soil and the following parameters: mixture ratio, age, proportion of solidifying agent, and degree of compaction, is obtained, and the mixture ratio is, for the purpose of optimum strength, from 1∶200 to 1∶400, which may be referred to in the future theoretical study and practical reference.
