摘　　要：通过室内试验对二灰土在恒温箱低温养生、养护室标准养生和暴露养生这三种养护条件下石灰剂量的衰减规律进行试验研究,得出的二灰土底基层施工中养护条件、实测灰剂量与龄期之间的相互关系,可为施工单位掌握二灰土石灰剂量变化情况提供依据,并为制定出科学可行的施工组织计划和检测标准打下基础。This paper studies the change of lime reduction of lime-ash soil under the following three conditions in an inside experiment, such as low temperature, stable temperature and exposed found. The relations among the different condition, lime content and ages in lime-ash soil construction process are drawn, which can provide reference for construction units to grasp its changes rules, and lay a foundation for making feasible construction plan and measurement criterion.
