粉喷桩加固公路软土地基质量控制研究

Quality control study on soft soil foundation of cement injection pile reinforce highway

公路工程建设过程中,软土地基沉降控制问题越来越受到重视,成为路基工程质量控制的关键环节。文章结合具体工程实际,以粉喷桩加固公路软基为例,建立有限元数值模型,对不同桩长、桩间距、桩径条件下粉喷桩处治公路软基沉降控制效果进行对比分析,确定不同处治方案对于控制公路软土地基沉降的作用和效果,为制定合理的工程处治方案奠定基础。

During highway engineering construction process, the problem of soft soil foundation settlement control received more and more attention, become a key link in the process of suhgrade engineering quality control. Combining with specific engineering practice, takes cement injection pile reinforce highway soft soil foundation as example, establishes the finite element numerical model, conducts eontrastive analysis on the soft soil foundation settlement under different pile spacing, pile length, pile diameter, confirms the role and effect of different treatment schemes for controlling the settlement, which lay a foundation for the development of reasonable engineering treatment scheme,
