| 摘 要： | 水泥土连拱抗滑墙加固软基边坡,能够充分发挥水泥土抗压能力和抗剪能力,同时从机理上避免弯折效应而又能有效消除随机劣质层的影响。本文对水泥土连拱抗滑墙加固结构的工作性状进行了系统的研究,探讨了加固结构设计参数的变化对边坡抗滑效果的影响。分析了墙厚、连拱抗滑墙进入硬土层深度、抗滑墙长度等参数对加固效果的影响,为工程应用提供了理论指导。

Research on Reinforcement Structure Optimization of the Cement-soil Arched Walls |
| |
| Abstract: | A new structure of cement-soil mixing pile is raised to improve the anti-slide reinforcement of soft ground embankment. The cement-soil arched walls embedded in the soft subsoil will transfer lateral forces in reasonable ways. Detailed research shows that the structure of arched walls can greatly increase slope stability and reliability. A systematic behavior analysis of the cement-soil arched walls is carried out to study the influence of the variation of structural design parameters to the retaining effeets. The factors such as pile diameter,depth of arched walls into the hard soil,length of the sliding wall ,are taken into account to analyze the retaining effeet. Through the analysis ,the reasonable values for these parameters are pointed out which can be applied as a theoretical guide for engineering practice. |
