压密注浆技术作为实用性较强的工程技术,其在软土地基加固处理中应用较为广泛,但较小应用到公路软基加固中。本文通过结合某公路路基加固的工程实例,分析压密注浆在公路路基加固中的作用机理出发;针对工程特点提出可行的压密注浆方案,提出各项的施工参数选取,通过试验定取参数用于施工;同时分析公路路基加密注浆前后土体的物理力学性质变化,表明注浆技术的可行性。
Compaction grouting technology as a practical engineering technology, its application in the consolidation of soft ground reinforcement is more widely used, but smaller applications to the soft ground reinforcement. Based on the engineering examples of the reinforcement of a highway subgrade, this paper analyzes the action mechanism of compaction grouting in the reinforcement of highway subgrade. According to the characteristics of the project, a feasible compaction grouting scheme is put forward, and various construction parameters are selected. The parameters are used for construction. Meanwhile, the change of physical and mechanical properties of soil before and after encryption grouting of roadbed is analyzed, which shows the feasibility of grouting technology.
