摘要

研究目的:随着西部地区大量基础设施建设的实施,尤其是铁路建设,不可避免地遇到大量黄土高边坡。大量的黄土边坡灾害严重影响着西部经济建设,危害行车安全。黄土边坡变形破坏机理及稳定性研究分析是其预测预报的基础,通过研究可在工程设计和维护中作为设置防治措施的依据。
研究结论:将黄土高边坡按坡体结构分为新黄土边坡、新老黄土边坡、老黄土边坡、新黄土+基岩边坡、新老黄土+基岩边坡、老黄土+基岩边坡6种类型;分别对其变形破坏类型、特点、形成机理及其危害进行了分析,建立了黄土边坡稳定性定性评价标准;通过对太中铁路沿线黄土高边坡稳定性统计分析,提出了黄土边坡防治的建议。对铁路沿线黄土高边坡设计防护具有一定的指导意义。

Abstract

Research purposes:With constructions of infrastructures and railways in west China,it is inevitable to encounter a large number of high loess slopes.The disasters caused by the loess slope have seriously affected the economic construction and harmed the traffic safety in west China.The researches have done on the deformation failure mechanism and the stability of loess slope for the purpose of providing the basis for predicting the disasters of high loess slope and taking the control measures for the disaster in the design and maintenance.
Research conclusions: The loess slope can be divided into 6 types:neo—loess slope,old+neo—loess slope,old loess slope,the neo—loess+bedrock slope,the old loess+neo—loess+bedrock slope and the old loess+bedrock slope.The styles,characteristics,formation mechanism and the hazard of deformation failure of these six types of slope are analyzed,and the stability evaluation criteria for them are worked out.Through the analyses of the stability of loess slope Mong the Taiyuan—Zhongwei Railway,the control measures for the disaster of loess slope are suggested with the certain significance to the loess slope along railway line.
