摘要
堆载预压不仅可以应用在路基施工阶段,也可以应用于路基填筑结束后的自稳期。堆载预压可以显著加速路基沉降,从而减小路基工后沉降。传统堆载预压技术,习惯采用土载预压方案,此方案非常容易影响当地生态环境,同时还会滋生出弃土转运及治理问题。本文立足于生态环保及资源节约视角,依托某高速公路软土路基处理的工程实践,分析了水土联合堆载预压方案的技术原理,总结了此联合措施的技术要点。
Surcharge preloading can be applied not only in the subgrade construction stage,but also in the self stabilization period after the completion of subgrade filling. Surcharge preloading can significantly accelerate the subgrade settlement,thus reducing the post construction settlement of subgrade. The traditional surcharge preloading technology is used to adopt the soil preloading scheme,which is very easy to affect the local ecological environment,and at the same time,it will breed problems of spoil transfer and treatment. Based on the perspective of ecological environment protection and resource conservation,this paper analyzes the technical principle of water and soil combined surcharge preloading scheme,and summarizes the technical points of this combined measure,relying on the engineering practice of soft subgrade treatment of an expressway.
