考虑侧向土压力影响的水泥土搅拌桩设计

水泥土搅拌桩是就地将软土和水泥搅拌在一起的一种加固地基。在地下处于三向受压状态。针对水泥土搅拌设计中存在简化受力情况的问题，在分析桩全则向土压力和水泥土三向受压强度的基础上提出了考虑侧向土压力影响的水泥土搅拌设计方法，工程实例计算表明，应用该方法进行设计，可达到节约水泥，降低工程造价的目的。

A Design of Cement soil Mixed Piles Considering Influence of Soil Pressure from Pile Sides

Built piles made of cement stirred with soft soil in situ is widely used in many aspects of building engineering.These piles,applied by triaxial underground compression,are one of measures for ground stabilization.Because of the existence of simply forced pile in design,the thrust and triaxial compression strength exerting the body of pile are analysed,and a design method is proposed for this cement soil stirred pile.An example given here demonstrates that the method is capable of saving the amount of cement usage and decreasing cost for construction.
