| 摘 要： | 作为黄土地区一种重要的不良地质现象,黄土洞穴对各种工程都造成了不同程度的危害,其中以对公路的危害最为突出。黄土洞穴对公路路基、边坡、桥梁、隧道和排水设施都有不同程度的危害,而且这些危害在型式、主要危害的部位及危害的严重程度等方面都有一定规律。为了从根本上认识黄土洞穴对公路的危害的规律和机理,指导公路黄土洞穴稳定性评价和防治,本文在对陕西省和甘肃省公路黄土暗穴调查的基础上,根据黄土洞穴对公路工程不同部位的破坏特征总结出黄土洞穴对公路路基、边坡、桥梁、隧道和排水设施危害的地质模式和致灾机理。

| Abstract: | As an important hazardous geological phenomena,caves in loess area have caused loss and damages to various constructions.In particular,the loss and damage to highways are the most distinctive.Site investigation proves that caves in loess have led to different damages to road bed,slopes,bridges,tunnels and drainage facilities of highway.Such damage shows certain regularities in the types,positions and degrees.To understand the essential regularities and mechanisms of the damage caused by caves in loess and guide the stability evaluation and prevention of caves of highway in loess,the geological mode and mechanism of damage of caves in loess to road bed,slopes,bridges,tunnels and drainage facilities of highway are summarized on the basis of widespread site investigations on the highways in Shaanxi and Gansu provinces. |
