高压旋喷桩在软基加固中若干问题探讨

Discussion on Some Problems of High-pressure Jet Grouting Pile for Reinforcement in Soft Ground

摘要:

结合工程经验，重点对高压旋喷桩在路基和铁路桥墩基础加固中影响桩体强度因素，影响桩体截面因素，设备机具选择与成桩质量效率的相关性，浆液质量控制与成桩质量的相关性，几种特殊地层的技术措施等相关技术问题进行了探讨。

Abstract:

With engineering experience, discussion was made on influence factors for high-pressure jet grouting pile in reinforcement of roadbed and foundation of railway bridge pier, influence factors for cross section of pile, correlation between selection of equipments and piling quality and efficiency, correlation between slurry quality control and piling quality, and technical measures for some special stratum.
