| 摘 要： | 针对高压旋喷咬合板加固铁路填方路堤的效果问题,基于FLAC3D程序,建立了简化的路基计算模型,分析了三维状态下的原状路堤、高压旋喷咬合板加固路堤的沉降及应力状态。研究发现,经高压旋喷咬合板加固后的路堤,路堤的整体性提高明显,桩体及路堤各层受力更为合理。

Numerical Simulation Analysis of Reinforcement of Railway Embankment by High Pressure Jet Grouting Bite Plate |
| |
| Abstract: | In relation to the reinforcement effect of high pressure jet grouting bite plate on railway embankment, the simplified subgrade calculation model was established on the basis of FLAC3D program to analyze both the settlement and stress state of embankment undisturbed and reinforced by high pressure jet grouting bite plate under three dimensional conditions. Through the study, it was found that the embankment reinforced by high pressure jet grouting bite plate has greatly improved integrity with the more reasonable force state in the pile body and each layer of embankment. |
