| 摘 要： | 高速铁路要求轨道有很好的平顺性,对路基的稳定性和变形更有严格要求。以东部沿海某高速铁路为背景,研究了在长期循环荷载作用下,深厚软土层地基倾斜基底的倾角变化,引起的软土强度折减,对桩-网复合地基稳定性安全系数的影响,并探讨了影响桩-网复合地基稳定性安全系数的其他因素。

Analysis on Stability of Pile-net Composite Foundation for High-speed Railway on Sloping Base in Deep Soft Soil Strata |
| |
| Abstract: | High-speed railway requires excellent track regularity, and subgrade stability and deformation strictly. Taking a coastal high-speed railway in the east as the background, how the inclination change of sloping base in deep soft soil strata and the strength reduction of soft soil caused by long-term cyclic loading affect the stability safety factor of pile-net composite foundation, was studied, with the other impacts on this safety factor discussed. |
