摘 要: | 对软土地基处理方法中的深层搅拌桩地基的沉降计算方法进行了讨论,并研究分析了复合地基沉降的主要影响因素,分析结果表明直接影响复合地基加固效果和经济效益的重要因素分别为置换率、桩长和桩身强度,因此软土地基利用深层搅拌法进行加固处理时,应结合实际工程合理选取各参数,使得桩长、置换率、桩身强度三者达到最佳组合。

Abstract: | The method calculating the settlement of soft foundation stabilized with deep cement mixing pile method is discussed and the main factors affecting the settlement of such composite foundation are studied herein. The study results show that displacement ratio, pile length, and pile strength are the key elements directly influencing the reinforcement effect and economic benefit. Therefore, in the reinforcement of soft foundation with deep mixing pile method, the parameters shall be selected properly in combination with the practical project so as to reach optimized combination of pile length, displacement ratio and pile strength. |
