郑武客运专线地基土沉降与变形规律的试验研究

Experimental Research on the Regulations of Deformation and Settlement of Foundation Soils on Zhengzhou-Wuhan Passenger Dedicated Line

研究目的:获取郑州至武汉铁路客运专线沿线地基土的沉降与变形规律。研究结果:选取代表性地区进行多组平板载荷试验,获得了沿线广泛分布的粉质黏土的变形特性及时效关系,分析了温度和前期固结压力对沉降的影响,最后提出了加固建议措施。

Research purposes:This paper gets the regulations of deformation and settlement of foundation soils on the passenger dedicated line from Zhengzhou-Wuhan PDL. Research results:A series of plate loading tests were conducted at the representative places.And the character of deformation of foundation soils and the relationship of settlement and time have been got at the areas of silty clay distributed extensively along the passenger line.Meanwhile,the effects of the temperature and pre-consolidation pressure in...
