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 soil areas are widely distributed in our country, a large number of roads due to conditions and built on the soft soil foundation. Due to its high water content, high compressibility and low bearing capacity, soft soil has a great impact and hidden danger to highway construction. Based on the monitoring data, the subsidence method was used to calculate the settlement and compared with the measured settlement, the settlement of the foundation was analyzed by finite element method and compared with each other The practicality of the method, and finally put forward the settlement correction factor that is more suitable for the characteristics of the area.
