摘　　要：采用塑料排水板超载预压法进行特殊路基的设计和施工,并通过对软土路基的变形监测结果进行了分析,评价其安全性。监测结果分析表明,在等量超填土4.5 t/m2预压3个月后固结度普遍达到85%以上,软土路基固结速度很快,且路基在堆载过程中是安全稳定的。实践证明,用塑料排水板超载预压法处理深达20余米、承载力极低的淤泥质粉质粘土排水效果明显,设计与施工方案是可行的。The paper introduced the application case and measurement on the spot with surcharge preloading plastic drainage to treat soft ground in the roadbed of silty and powdery clay of Shunde City. The statistical analysis of the result of deformation monitoring indicated that the consolidation was very fast and the roadbed was steady and safe in the stack process. This technique of municipal road construct is feasible in the design and the construction of project.
