通过对国内外现有无粘性土抗剪强度研究进展的分析,结合新疆地区碎石类土特有的土质盐分含量大、颗粒间化学胶结效应明显等特点,提出由常规实验方法并不能获得真实的粘聚力值,指出现阶段对碎石类土粘聚力取c=0的作法是不合理的。用现场大型直剪试验辅助大量的工程实例进行强度参数反分析,是解决此类问题既经济又有效的方法。
Based on the analysis of the research progress of the existing non-cohesive soil at home and abroad, combined with the characteristics of large soil salt content and obvious intergranular chemical agglomeration in the gravel soil in Xinjiang, it is proposed that the conventional experimental method can not obtain the true Cohesion value, referring to the current stage of gravel soil cohesion take c = 0 approach is unreasonable. It is an economical and effective way to solve such problems by using a large-scale on-site large-scale direct shear test to assist a large number of engineering projects to conduct back analysis of strength parameters.
