摘要： 在山区铁路建设中，经常会遇到高填深切路段，尤其是站场场坪建设不宜采用桥、隧工程措施的地段，在进行支挡结构设计时既要考虑结构的安全稳定性，还要考虑到场坪的排水、临近河道段填方是否压覆河道、以及河流的冲刷、掏切对结构变形的影响，同时还应考虑到支挡结构与自然环境的协调性。加筋土格宾桩基承台挡墙采用刚性与柔性结合的支挡结构，能很好的适应上述因素。结合具体工程设计应用，详细论述了加筋土格宾桩基承台挡墙的设计方案和施工要求，为山区场坪边坡设计提供一种安全、环保的设计理念。

Abstract: High embankments and large cut slopes are frequently encountered in the railway construction in the mountain areas. Especially, for locations such as platform for stations, where the bridge and tunnel structures are not feasible, fill embankments are frequently used and retaining walls will be required. In the retaining all structure design, in addition to the stability, the drainage, river bank protection, potential scour, and it impact on the retaining structures should be considered. Finally, the compatible with the adjacent environment is also an important factor. The pile supported gabion faced MSE walls can meet these requirements.
