摘　　要：水土联合堆载预压技术是公路工程中针对软弱路基进行处理的常用技术。水土联合堆载预压技术的应用可以加速填筑路基的沉降,减少因施工产生的不均匀沉降,从而有效提升路基的施工质量,增强整个公路工程的路基稳定性。传统的土石预压技术所用土方量较大,对生态环境的影响较大,且施工成本较高,对地域内的土方需求量较大。以新疆地区某公路工程项目软弱路基为研究对象,针对传统土石方堆载软弱路基段的缺点,提出了水土联合堆载预压技术,并进行了应用研究,同时对水土联合堆载预压技术的施工效果进行了分析。结果表明:水土联合堆载预压技术切实可行,可以有效保证路基的稳定性,为后续类似的公路软弱路基处理项目提供了借鉴。Water-soil combined surcharge preloading technology is a typical technology used in the disposal of soft subgrade in highway engineering.The application of water-soil combined surcharge preloading technology allows the acceleration of the settlement of the filling subgrade,reduction of the uneven settlement caused by construction,effective improvement of the construction quality of the subgrade,and the enhancement of the stability of the subgrade of the whole highway project.The conventional earth-rock preloading technology involves a large amount of earthwork,which has a great impact on the ecological environment.At the same time,the construction cost is high,and the demand for earthwork in the region is enormous.Taking the soft subgrade treatment of a highway project in Xinjiang as a case study,aiming at the shortcomings of the traditional earth-rock piled soft subgrade section,the water-soil combined surcharge preloading technology was proposed and applied.At the same time,the construction effect of the water-soil combined surcharge preloading technology was analyzed.The analysis results confirm the feasibility of the water-soil combined surcharge preloading technology and its effectiveness in securing the safety and stability of the roadbed,thus promoting a reference for future similar highway soft roadbed treatment projects.
