摘要
软土地区修建高速公路必须保证的稳定,路基的工后沉降必须控制在允许的范围。某高速公路穿越泻湖软土地区,地质勘察揭示分布大量的淤泥和淤泥质软土,由于工程特性较差,为保证实际工程加固处理的效果,开展了相关淤泥质软土及不同掺入比和不同龄期的水泥土的强度试验研究,分析了水泥土强度增长的因素和复合地基承载力的理论探讨,以确定相应的设计参数,为淤泥质软土的处治方案的确定提供依据。
The expressway engineering construction have to make sure the stability of embankment and smaller post-construction settlement.For an expressway in the soft soil district of lagoonal deposit,geotechnical investigation is made and shows that the soft soils are muck and mucky soft soil. As the engineering characteristics of mucky clay is very poor,the method of foundation improvement has to be studied in general. In the paper,the strength features of mucky cement soil are investigated in different percentage of cement and different curing time. Meanwhile,the effective factors of cement strength are analyzed.
