水泥土墙在组合式挡土支护结构中作用的探讨

Exploration on the role of cement wall in combined soil retaining support structure

结合具体工程实例,介绍了"深层搅拌桩+灌注桩组合式挡土支护结构"在工程中的应用,归纳了施工先后顺序和水泥土墙采用高压旋喷桩或深层搅拌桩的优缺点,进而引发了进一步考虑深层搅拌桩的作用如何去量化的问题。

Combining with specific engineering practice,it describes the application of ＂deep mixing pile＋combined grouting pile retaining support structure＂ in the project,summarizes construction sequence and advantages and disadvantages of using high-pressure jet grouting pile or deep mixing pile on cement wall.Furthermore,it leads to consider how to quantify the function of deep mixing pile.
