高填方路堤沉降的有限元分析

Finite Element Analysis of Settlement on High Embankment

高填方路堤具有沉降大,沉降时间长,对地基承载力要求高等特点.有效地降低路堤沉降,消除路堤沉降所带来的危害已经成为公路建设领域的一个重要课题.结合某二级公路的工程实际,对高填方路堤的沉降变形的影响因素进行有限元分析,为预防路堤的沉降变形过大,保证路堤的稳定性提供有效的依据,为以后类似地区的类似工程起到借鉴作用.

Distinguishing from the ordinary roadbed, the high embankment has the characteristics of much settlement, long-time settling, high demand for carrying capacity of foundation and so on. How to reduce the settlement of embankment effectively and to dispel the endangerment of settlement caused is a great problem in the domain of highway. Based on a second class highway example, the settlement and distortion of high embankment are discussed through finite element analysis. Some valuable references for predicting settlement and distortion are provided and the stabilization of embankment is ensured.
