| Abstract: | 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. |
