京珠高速公路粤境北段路堑高边坡失稳防治研究

Research on disaster prevention and control for roadcut high-slope in northern Guangdong Province of Jing-Zhu expressway

京珠高速公路粤境北段地形地质条件十分复杂,被世界银行专家称为"中国最具挑战性的公路项目"。文章介绍了针对此项目开展的路堑高边坡失稳防治研究情况,着重介绍了该项研究的技术路线,以及为预防路堑高边坡失稳开展的系列研究。即:①路堑高边坡工程地质条件;②按常规所做原设计的堑坡稳定性;③路堑高边坡设计方案;④路堑高边坡施工工艺;⑤动态监测;⑥动态设计。研究与设计施工密切配合,及时将研究成果应用到工程实践中,取得很好的效果。

JingZhu expressway in northern Guangdong has very complicated toporaphical and geological conditions and is called 'the most challenging project of highway in China' by the experts from World Bank. This paper introduces the research on disaster prevention and control measures for roadcut highslope of the project particularly on the technical method of the project research and a series study on damage prevention of roadcut highslope, i.e., 1) engineering geological conditions of roadcut highslope;2) roadcut sideslope stability of original design by conventional method;3) roadcut highslope design; 4) construction technology of roadcut highslope; 5) dynamic monitoring; 6) dynamic design.Due to the combination of construction design and research, and the timely application of study result to engineering practice,good effect has been achieved.
