| 摘 要： | 用真空预压法对某泵站进水渠在施工期滑坡的堤基进行加固,通过对加固过程中的监测成果及加固前后的检测成果进行分析,得出了预压区内土体的沉降变化规律、深层水平位移变化规律,依据实测沉降过程线计算出预压60 d后的渠堤土体固结度,并对加固效果进行了评价.真空预压使得渠堤土体的物理力学指标达到了设计要求,加固效果明显.

| Abstract: | Vacuum prepressing method can be applied to improve the foundation of bank in a pumping station. The laws of consolidation settlement and horizontal displacement were found through the analyses of field monitoring and results of test before and after strengthening. The degree of consolidation of soil of the bank was calculated by duration curves of measured settlement drawn from field monitoring data after prepressing sixty days The result of reinforcement was verified to be satisfactory. |
