道路软基路堤的沉降动态控制方法研究

Study on Dynamic Settlement Control Method of Road Embankment with Soft Foundation

地质勘查及地基处理方案,这两种因素皆会左右施工沉降量的推算。基于此,结合某市政道路软基路堤处理项目,探讨沉降动态控制方法。明确软基地质勘查意义,并针对常见的软基加固方案——括换填法、抛石挤淤法、堆载预压法或水泥搅拌桩进行论述。其中以堆载预压法为例展开分析,对施工方案设计及固结沉降计算两方面内容进行详细介绍,最后提出沉降动态控制方法,为类似工程提供参考。

These two factors of geological survey and foundation treatment scheme will influence the calculation of construction settlement.Based on this,combined with a municipal road soft foundation embankment treatment project,the dynamic settlement control method is discussed.The significance of soft foundation quality exploration is made clearly.The common soft foundation schemes of replacement method,riprapping method,preloading method and cement mixing pile method are discussed.The preloading method as an example is analyzed.The design of construction scheme and the calculation of consolidation settlement are introduced in detail.Finally,the dynamic settlement control method is proposed,which can be referred for the similar projects.
