| 摘 要： | 注浆法是提高软土地基承载力和控制其压缩沉降的传统加固方法,由于其过程不可控性与加固效果的不确定性,在应用于加固运营地铁隧道下卧土时,须考虑加固过程的扰动及长期效果。通过现场试验,研究注浆加固的工艺参数对饱和软土扰动和加固效果的影响,以获得安全合理的精细化注浆工艺参数,对处理软土地铁隧道长期沉降问题具有现实意义。

| Abstract: | Grouting is a traditional reinforcement method to improve bearing capacity of soft soil and control the compression settlement.However,it has been criticized by engineers for its uncontrollable process and indeterminate reinforcement effect shown by long-standing engineering practice.When grouting is applied to reinforcing the underlying soil of subway tunnel,it needs taking the disturbance during reinforcing process and the long-term effects of grouting into consideration.It is of practical significance to study the effects of grouting parameters on disturbance of saturated soft soil and ultimate reinforcing effect.Therefore,this in-situ test was carried out to obtain reasonable parameters during grouting process. |
