( Wuhan Qiancheng Geotechnical Engineering Co., Ltd., Wuhan 430062, China)Abstract: In recent years, cement sand mixing piles are used in soft ground enforced engineering. It requests different design and technological parameter according to different geology factor. This article introduces technology thesis, design method, equipment, work process, quality controlling and detection of multi-direction cement sand mixing pile, using in high-speed railway soft-ground enforced engineering. This article introduces field experiment and application about multi-direction cement sand mixing pile in new Xiang-Pu Railway Nanchang Hinge project. Using reasonable program and technology parameter, this project gets a good efficacy. Base on this project, this article summarizes the research and application about multi-direction cement sand mixing ground in high-speed railway ground treatment, and give reference to similar project.
Keywords: multi-direction cement sand mixing pile; mixing ground bearing capacity; non-side-limit pressive strength; ground enforcing
