摘　　要：以深圳市宝安图书馆软基处理工程为研究对象,借助大型通用非线性有限元软件ABAQUS,研究了塑料排水板打设深度、排水能力和间距对软基处理影响规律:塑料排水板间距、排水能力和打设深度对软基处理的效果较明显,其打设深度尤为敏感。Taking the soft foundation treatment project of Shenzhen Baoan Library as the research object, this paper studied the rule how plastic drainage plate＇s driven depth, drainage capacity and its spacing affect soft foundation treatment, with general nonlinear finite element software ABAQUS. The result shows that the effect of the driven depth, drainage capacity and spacing on soft foundation treatment is obvious, especially the driven depth is sensitive.
