水泥搅拌桩在淤泥中加固机理及施工质量控制

为了保证上部结构的安全、正常使用,往往需预先对淤泥进行加固处理,通过对珠海西区多个水闸工程的软土地基处理试验,建立了粉喷深层搅拌法用于地基加固的工程质量控制及评定标准,以进一步拓宽深层法在水利工程的应用,探索适应软弱淤泥地层的更合理有效的加固手段。

The cement mixing pile strengthening mechanism and construction quality control in mud

In order to make sure upper structure safety and normal utilization, the mud was need to be strengthened treatment previously. The paper through treating test on multiple lock engineering soft foundation in Zhuhai, the powder jetting deepen mixing method was built to use in foundation strengthening engineering control and evaluation standard, so as to further widen deepen method application in hydraulic engineering, and explore more proper and effective strengthen method to adapt soft mud foundation.
