河道工程整体稳定计算中水泥土粉喷桩抗剪强度指标选取讨论

Discussion on Selection of Shear Strength Indexes of Cement Injection Pile in Calculation of Overall Stability of River Engineering

目前国内各行业规范及国标对于水泥搅拌桩抗剪强度指标的计算均未提及,通过分析现有规范及其他资料,并结合工程实例,对河道工程中水泥土粉喷桩抗剪强度指标、复合地基综合抗剪强度指标及边坡的整体稳定进行分析,以供类似项目借鉴。

At present,the calculation of the shear strength indexes of cement mixing pile has not been mentioned in various domestic industry specifications and the national standards.By analyzing the existing specifications and the other details,and combined with an engineering case,the shear strength index of cement injection piles,the comprehensive shear strength index of composite foundation and the overall stability of the slope in the river engineering are analyzed in order to provide the reference for the similar projects.
