Experimental Research on Jet Grouted Micro Piles in Soft Soil Area

摘要:

软土地质条件下建筑物的沉降变形和承载力要求越来越高，对基础施工工艺提出了较高要求。在高压旋喷施工工艺的基础上，提出旋喷式插筋微型桩施工工艺，开展了微型桩工艺试验研究，结果表明该工艺大幅提高了单桩桩基承载性能，为实际工程应用提供了技术数据支持。

Abstract:

Under the condition of soft soil, the requirements of buildings on settlement deformation and bearing capacity are getting higher and higher, leading to higher requirements on the foundation construction. Based on the high-pressure jet grouting process, the micro-pile construction process with jet grouting was proposed, and tested. The results show that the process greatly improves the bearing capacity of the single-pile pile foundation and provides data support for field applications.
