浅谈桩板式挡土墙的设计与应用

Brief Discussion on the Design and Application of Sheet-pile Retaining Wall

桩板式挡土墙是在桩间设置挡土板等结构来稳定土体的支挡结构,承受荷载主体为抗滑桩,因其结构特点,有着施工作业面小、占用土地少的优势,多应用在铁路支挡、山体边坡治理及房屋建筑中。滨海公路某路段受占地条件限制,无法进行路堑边坡开挖,经过技术比选,采用桩板式挡土墙进行路堑支挡,既解决了占地问题也最大程度地保证了边坡稳定。

Combining with the engineering situation of the high slope control blasting construction technique in Jinjingwan Road of Pingtan Comprehensive Experimental Plot, the paper introduces the blasting design scheme and its protective measures.
