“5·12”汶川地震区都汶路老虎嘴崩塌体治理
|
摘要
距"5·12"汶川地震震中映秀2.8km的都汶路老虎嘴崩塌体,是本次地震中岷江上游最具影响的一处次生灾害,规模巨大,性质特殊,其处治工程思路与一般工程设计更是不同。在认识该崩塌体本底条件的基础上,分析其形成、发育特性及未来发展趋势,提出并实施的固坡桩技术、安全备用平台就是其中两种有别于一般设计的特色工程。
Laohuzui rockfall which is 2.8 km away from the Yingxiu——"5·12" epicenter was the most influential sub-disasters on the upstream of the Minjiang River. Because it was Magnitude and the nature is special, the remediation is totally different from the general engineering designs. In this paper, authors based on knowing the background of the rockfall body condition, analysised the rockfall formation and development characteristic, then forecasted development trend. The authors also roposed a solid slope pile technology and reserveing platform of security design which are two special designs
