摘要
对陕西省210国道在2002年经历洪水造成公路路段的灾害情况作了调查和介绍,应用土力学原理和路基工程防护方法,分析研究了路基挡土墙和山区公路不同类型的路基防护结构物的作用及其适用条件。结果表明,通过受力分析计算所确定的路基挡土墙和路基防护结构物尺寸,才能满足在洪水侵袭时的强度和抗倾覆的安全要求。
An investigation of roadbeds damage caused by flooding at 210 national road in Shaanxi Province section in 2002 was carried out.Using soil mechanics principle,the different type of roadbed protective structures of mountain highways,their actions and suitable conditions are analyzed.The results indicate that the section sizes of roadbed protective structures should be determined through calculation under loading,therefore,the roadbed has enough strength and antioverturn capacity during flooding.
