| 摘 要： | 中国西部地区等级较高的地震，常常发生在岩体强度高的深切割地貌区，因而震后次生灾害的危害预测和防治显得尤为重要。以G213映秀至汶川公路抢险保通的工程实践为例，总结了极震区崩塌灾害对公路造成的危害，结合震区地质环境，对崩塌物源的危岩体的发育和崩塌体运动规律进行了分析，并探讨了危岩体防治措施。供类似工程参考。

| Abstract: | Earthquake with large magnitude in Western China arises often in such area that the rockmass has high strength and it presents deep cutting landform, then the hazard prediction and prevention against secondary disaster after the earthquake are most important. Taking the practice of road emergency rescue on G213 Yingxiu-Wenchuan Highway as an example, this paper summarized the hazards caused by rockfall to highway in meizoseismal area, and combined with the geological environment therein to analyze the laws of the development of dangerous rock, the rockfall source, and the movement of falling rock, by which the prevention measures related were discussed. For reference by similar engineering. |
