关于路桥过渡段沉降防治的结构设计

Structural design to control settlement of transition section between pavement and abutment

为了解决台背过渡段的差异沉降问题,从台背地基处理、桥头路基设计和路面处理等方面探讨了常用处理方法,介绍了目前国内常用软基处理的方法,结合台背沉降防治措施,提出用于台背回填区的结构设计方法,以有效防治桥头跳车。

In order to deal with differential settlement of transition section behind abutment, from behind abutment foundation treatment, roadbed design at bridge head, pavement treatment and other aspects common treatment methods are discussed. Combined with soft roadbed treatment methods at home and abroad practical structural design method is proposed for back fill area behind abutment in order realize effective oontrol of vehicle jolting at bridgehead.
