水泥土搅拌桩复合地基按沉降控制的优化设计研究

Study on Optimum Design According to Settlement Control of Cement-soil Mixing Pile Composite Foundation

水泥土搅拌桩复合地基在软土地基处理工程中被广泛应用。其计算设计理论已相当成熟。但目前的计算设计方法相对保守．需进一步优化。本文分析了常规按沉降控制设计的特点．提出利用最优理论优化水泥土搅拌桩复合地基的方法。结合工程实例．对水泥土搅拌桩复合地基进行优化设计．以期达到更好的经济效益。

Cement-soil mixing pile composite foundation is commonly used in soft soil foundation treatment project. The calculating design theory of which is quite mature. But the current calculating design method is relatively conservative, and it need further optimization. This paper analyzes the characteristics of routine control design according to the settlement, and it proposes the method to utilize optimum design theory to optimize cement-soil mixing pile composite foundation. Combining pratical projects, the cement-soil mixing pile is optimized to obtain better economic benefits.
