摘要
以四川省绵阳地区的饱和软粘土为研究对象,通过对软粘土的能谱分析试验分析了该土的矿物成分和微观结构组成,探讨了软粘土劈裂注浆的设计方法和要点,得到注浆压力与注浆量随时间的变化曲线,扫描电镜图和加固前后物理参数的对比表明劈裂注浆加固软土效果显著。
Based on scanning electron microscopy and X-ray spectrometer,the common trace elements of the saturated soft clay of Mianyang were determined.The design method of the soft clay was discussed and the amount of grouting and pressure with time curve were obtained.From the photo and the physico-mechanical parameters of reinforced original soil,we can see that split grouting reinforcement of soft soil marked effect.
