摘要
在假设桩体和桩周土体均服从莫尔-库仑强度准则的前提下,采用FLAC-3D软件来研究钉形水泥土搅拌桩在桩顶荷载作用下桩身荷载的传递规律,并对其特征参数进行分析。结果表明:钉形水泥土搅拌桩桩身内力分三阶段衰减;单桩设计参数对其特征参数影响较大。在工程设计中应选择合理的单桩设计参数,使其特征参数控制在理想范围内。
On the assumption that pile and its around soil are submit to Mohr-Coulomb strength criterion, FLAC-3D software was used to study the load transmission law of T-shaped cement-soil mixing pile under pile top loads. In the meantime, characteristic parameter of the pile was analyzed. Results show that internal force of T-shaped cement-soil mixing pile suffers from attenuation in three phases, and design parameters of single pile remarkably influence on its characteristic parameter. In order to control its characteristic parameter in reasonable interval, proper design parameters of single pile should be chosen in the design of the project.
