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。针对水泥土搅拌桩设计中存在简化受力情况的问题，在分析桩体侧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桩设计方法。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。
The cement-soil mixing pile is a kind of reinforced foundation that mixes the soft soil and the cement in situ, and is in the three-dimensional pressure state in the underground. Aiming at the problem of simplified bearing conditions in the design of cement-soil mixing piles, based on the analysis of the lateral soil pressure and the three-dimensional compressive strength of cement soil, the design method of cement-soil mixing pile considering the influence of lateral earth pressure was proposed. . The engineering example calculation shows that the application of this method to design can achieve the purpose of saving cement and reducing the project cost.
