杂填土成分和工程性质复杂，若处理不当会因不均匀沉降造成其上构筑物的破坏。论文以位于垃圾填埋区域的铁路站场工程实例为背景，研究渣土桩加固杂填土地基的作用机理，并通过与杂填土注浆处理方案对比，分析两种方案地基处理前后的沉降量、承载力、动弹性模量等技术指标。结果表明：采用夯扩渣土桩承载力提高达2倍，动探击数提高2.5倍，动弹性模量平均提高1.2倍，而注浆处理效果并不明显，这说明渣土桩在处理大面积杂填土地基中具有良好的适用性。

Miscellaneous filled soil,with complex composition and engineering performance,is prone to induce uneven settlement or even the damage of the upper structure. Under such background,the paper takes reference from a railw ay station and yard project that takes place at a w aste landfill area,and looks into the application of slag pile and its mechanism in the reinforcement of miscellaneous filled foundation. The paper then compares its reinforcement results with that of grouting treatment,and introduces the technical index of settlement,bearing capacity and modulus of dynamic elasticity to analyzes the before and after performances of both schemes. The results indicate that thanks to the application of compaction slag piles,the foundation delivers twice the bearing capacity,2. 5 the dynamic penetration performance and an average of 1. 2 the modulus of dynamic elasticity. O n the other hand,grouting treatment fails to improve the foundation visibly,therefore it can be said that slag pile stands as a preferable choice in the reinforcement of large-scale miscellaneous filled foundation.
