摘要
根据长板-短桩复合地基的特点建立了简化的分析模型,获得了模型排水系统的解析解.由塑料排水板与砂井排水等效的原理得到了长板-短桩复合地基中地基土的等效渗透系数.利用有限元法和工程实例验证了长板-短桩复合地基排水系统简化分析的合理性和可行性.
The simplified analysis model was first established to get its analytical solution;and then the conversion function of soil permeability was conducted on the basis of equivalent drainage relationship between its drainage and sand well.Finally,the analysis results were verified to be reasonable and feasible by finite element method and actual project application.
