一、概述铁路沿线中小车站的房屋的特点是分散,建筑面积很小且多是修建在回填土上。而回填土往往仅用拖拉机推平及碾压,其均匀性和密实度很难达到地基基础设计规范的要求。如表1就是在郑州至商丘复线工程中,回填土抽样的试验数据,仅一组压实系数大于0.96,其余均不符合要求,不能作为天然地基使用。故探讨一种经济实用,施工方便的浅基础,以适应在铁路沿线中小站回填土上修健车站房屋,是一
First, an overview of the characteristics of small and medium-sized railway station along the railway is scattered, the construction area is very small and mostly built on the backfill soil. The backfill soil is often only tractor pusher and rolling, its uniformity and density is difficult to meet the requirements of foundation design specifications. As shown in Table 1, from the test data of backfill soil sampling in Zhengzhou-Shangqiu double-track project, only one set of compaction coefficient is greater than 0.96 and the rest do not meet the requirements and can not be used as natural foundation. Therefore, to explore a economical and practical, easy construction of the shallow foundation to adapt to the small station in the railway backfill repair station housing, is a
