【摘要】 针对京珠高速公路粤境北段软质岩路堑高边坡工程地质和水文地质条件,提出了锚固桩、预应力锚索桩、桩板墙、挡土墙及预应力锚索地梁等加固措施,以及结合加固边坡所采用的植被护坡技术。为保证合理组合的加固防护措施得到顺利实施,提出了分层稳定,逐级加固和坡脚预加固的施工方法。这些措施和方法对于软质岩路堑高边坡的稳定和安全具有重要的指导意义。更多还原

【Abstract】 Proposed in this paper are the measures of anchoring pile, prestress cable, pile plank, retaining wall and honeycombed wall for reinforcement of soft rock cut slopes of xiaotang-Gantang tong Project, Beijing-zhuhai expressway and in addition the vegtation protection technique is also suggested in combination with the reinforcing project. In order to ensure the implementation of the above reasonable combinative reinforcing and protectiog measures, the construction method of stabilization in layers, reinforcement in steps and presupporing of pile toes are proposed. The results of this paper are of important significance to the stability and safety of similar soft rock cut-slopes.更多还原
