刚性复合地基褥垫层技术

Cushion technology of rigid composite foundation

通过分析褥垫层在刚性复合地基中的作用,包括调整桩土应力,减小基础底面应力集中,调整桩、土水平荷载的分担等,说明了褥垫层是刚性复合地基设计的重要环节,必须合理选择褥垫层的厚度。

Based upon analysis of the actions of cushion in rigid composite foundation, which contain the adjustment of pile-soil stress, reduction of stress concentration of foundation bottom, adjustment of the distribution of horizontal load and so on the importance of cushion to rigid composite foundation design is elaborated. Author points out that reasonable thickness of cushion should be selected in design.
