摘要
软土地区在我国分布广泛,大量的公路由于条件限制而修筑在软土地基上。软土由于其含水量大、压缩性高、承载能力低的不利特点,给公路建设带来较大的影响和隐患。结合某道路真空-堆载联合预压处理软基试验段工程,根据监测资料,用分层总和法计算沉降量并与实测沉降量比较,用有限元数值分析法对地基沉降进行分析,比较各种方法的工程实用性,最后提出较适合该地区特点的沉降修正系数。
Soft ground zone distribute extensively in China, due to being limited by the conditions, a large number of highways must be constructed on the soft ground. Because of the negative characters of the soft soil, such as rich watercontent, high compressibility, low bearing capacity ere, biggish influence and hidden dangers are brought to the highway construction. Combining with the soft soil treating method of the trial pavement section, according to the monitoring data,settlement values calculated by hierarchical method is compared with the actual measurement settlement. The foundation settlement is analyzed by finite element analysis, and the engineering practicality of various methods are also compared.Finally, the auxiliary value of settlement suiting to the characteristics of region is brought forward.
