摘　　要：为有效控制水泥土搅拌桩复合地基的沉降,研究了沉降控制的理论设计方法。通过分析桩身长度、桩土置换率、褥垫层及水泥掺入量等关键因素,优化选择设计参数,并建立沉降计算模型。研究结果表明,该方法能合理设定沉降控制标准,有效评估设计参数对沉降的影响,为实际工程中的沉降控制提供技术参考,提高了水泥土搅拌桩复合地基设计的可靠性和准确性。In order to effectively control the settlement of the cement-soil mixing pile composite foundation,the theoretical design method of settlement control is studied.By analyzing key factors such as the length of the pile body,the pile-soil replacement rate,the cushion layer and the cement admixture amount,the design parameters are optimized and selected,and a settlement calculation model is established.The results show that this method can reasonably set the settlement control standard,effectively evaluate the influence of design parameters on the settlement,and provide technical reference for the settlement control in practical projects,so as to improve the reliability and accuracy of the design of the cement-soil mixing pile composite foundation.
