对垃圾土进行改性是降低工程投资,解决工程长期沉降问题的有效方法,发展前景极为广阔。通过对杨凌垃圾土的调查分析得出其含水率、干密度、各组成成分百分比等参数,以及垃圾土的级配参数,为改性试验提供了基础资料;开展了不同水泥石灰配比改性后垃圾土28 d龄期的强度、应力应变关系以及垃圾土的强度随龄期的变化规律试验。

Improving refuse soil is an effective method to reduce the project investment and solve the longterm settlement problems of engineering,which would have very broad prospects for development.In order to study both the physical index and engineering characteristics of refuse soil,the physicochemical tests were done for many groups of the refuse soil in Yangling.Some basic physical indexes of the refuse soil are obtained,such as the composition,water content,density and gradation and so on.These results could provide the basic data for improving the engineering characteristics of refuse soil.Some experiments have been done for the solid waste modified with cement and lime to study the curves of the stress-strain at 28 d maintenance period and the curves of the strength changing with the maintenance period of the solid waste.
