路堤本体主要是非饱和土,其变形由3部分组成,即瞬时压密产生的变形、主固结产生的变形和次固结产生的变形,因此其理论也应反映这3部分变形.以单轴压缩红层蠕变试验为基础,提出基于非饱和土单变量理论的红层非饱和土路堤沉降计算理论;通过算例对遂渝客运专线遂宁段某工点实际填筑过程的进行了数值模拟,并对其工后沉降进行了预则,结果表明,模拟结果与现场监测数据预测的结果相符,说明该理论是正确的?

Embankment body is composed mainly of unsaturated soils and its deformation included the three components, namely, deformation resulting from the instantaneous compaction, deformation of primary consolidation and secondary consolidation deformation,therefore, their theory should reflect the three-part deformation. Based on results of uniaxial compression creep test of red layers and unsaturated soil single variable, theory of unsaturated soil embankment settlement of red layers is put forward; through numerical simulation of embankment construction process of a worksite in Suining, railway line for passenger traffic from Chongqing to Suining, the deformation characteristics and predicted final settlements of numerical simulation are consistent with the field measurements,which shows that the theory is correct.
