CCG注浆过程的数值模拟研究
【提 要】:本文基于有限变形理论,采用点面接触模型模拟注浆过程中浆泡与土体之间的相互作用关系,通过拉格朗日方法引入这种相互作用关系,用约束变分原理建立适合模拟CCG注浆过程的控制方程。然后根据在试验中观察到现象建立的注浆过程模型编制的有限元程序可以动态模拟CCG注浆过程,为CCG注浆施工的优化设计奠定了基础。
【关键词】:CCG注浆有限变形点面接触模型数值模拟
Abstract: On the basis of the finite deformation theory,the theoretical study and numerical simulation are made on compaction using modified Lagrangian formula,the simulation is taken on viscous contact between mortar bubble and soil ground by point an surface contact control formula is set up to ada ...
