摘　　要：堆载预压是一种最常见的软弱路基处理方法,可显著提高软弱路基在填筑过程中的沉降速率,减小不均匀沉降,提高路基的稳定性与强度。一般来说,传统堆载预压主要以土石方作为载体,由于不利于生态环境保护,且运输过程中也会产生占用耕地、弃土运输费用高等问题,目前已逐步淘汰。基于此,本文以某高速公路项目为例,采取水土联合堆载预压施工技术对软弱路基进行处理,并通过跟踪监测,判断施工技术实际效果,以期为类似工程提供借鉴。Preloading is the most common method for treating weak roadbeds,which can significantly improve the settlement rate of weak roadbeds during the filling process,reduce uneven settlement,and improve the stability and strength of roadbeds.Generally speaking,traditional preloading mainly uses earth and stone as carriers.Due to its unfavorable impact on ecological environment protection and the high cost of occupying farmland and transporting abandoned soil during transportation,it has been gradually phased out.Based on this,this article takes a certain highway project as an example and adopts the soil water combined loading preloading construction technology to treat weak roadbeds.Through tracking and monitoring,the actual effect of the construction technology is judged,in order to provide reference for similar projects.
