路桥过渡段路基沉降填土方案及施工技术

Subgrade subsidence filling scheme and construction technology of road-bridge transition section

通过理论计算,研究了填土为石灰土和素土时的路基沉降规律,并结合工程实例,分析了路桥过渡段路基的沉降原因,从搭板设置、地基处理、台后填筑等环节,提出了路桥过渡段路基路面的施工技术。

Through theoretical calculation, the paper studies the subgrade subsidence law for the filling with lime soil and pure soil. Combining with engineering example, it analyzes subgrade subsidence causes at road-bridge transition section, and puts fonvard construction technologies of road-bridge transition section subgrade pavement from aspects of erecting-board setting, foundation treatment and filling.
