轻便触探检测水泥土搅拌桩浅谈

水泥土搅拌桩作为一种地基处理技术,正在被广泛的应用,但是,在如何采用轻便触探来判定搅拌桩的桩身强度及成桩均匀性等方面,相关的规范没有可操作性标准。本文结合规范及工程实际情况,提出了轻便触探击数N10与强度对应关系、不同水泥土龄期所对应的轻便触探击数及成桩均匀判定标准等,因此,使之真正具有可操作性的一种检测手段。

Testing of Soil-cement pile by Light dynamic sounding method

As a kind of soft soil reinforcement techniques,soil-cement piles are widely used.However,according to the related codes,it is difficult to evaluate pile strength and cement homogeneity by the light dynamic sounding.Based on the code and practical experience,the paper presents the relationship between N10 number and pile strength,points the relationship between different age strength and N10 number,and make the standard to evaluate the cement homogeneity,which make light dynamic sounding become a feasible m...
