摘要
研究目的:为配合京沪高速铁路的建设,解决在饱和松软土地基上修筑高速铁路的难题,铁道部批准开展《高速铁路液化土地基加固技术的试验研究》项目,目的是选取合理有效的饱和松软土地基、路基加固措施,控制路基地基的稳定性和沉降变形。研究结果:碎石桩和CFG桩桩网结构地基均明显减小了因地基液化引起的响应加速度放大作用,均能够有效地减小地基路基在地震条件下的沉降及不均匀沉降,提高地基路基的整体抗震性能。
Research purposes:In coordination with construction of Beijing-Shanghai High-speed Railway to overcome the hard difficulties of building high-speed railway on saturated weak soil foundation,Ministry of Railways approves the project of"Test and Research on Reinforcing Technology for Liquefied Soil Foundation of High-speed Railway"for the purposes of selecting and taking the rational and effective measures for reinforcing saturated weak soil foundation and subgrade in order to control the stability and settle...
