喷锚支护技术在市政道路工程中的应用

Application of Shotcrete Rock Bolt Support Technique in Municipal Road Engineering

喷锚支护是应用于矿山、隧道开挖或建筑物深基坑支护中土坡稳定的一项新技术,目前在西部市政道路边坡防护中应用较少。该文结合市政道路整治工程中边坡加固、防护的工程实践,从方案选择、设计、施工、工程体会等方面对喷锚支护技术进行了介绍。实践表明,该技术具有适应性强、经济性好、施工周期短、安全可靠等诸多优点,值得在市政道路整治的类似工程中推广应用。

The shotcrete rock bole support is a new technique applied in the soil slope stabilization of the mine,tunnel excavation or the deep pit support of buildings.At the present,it is less applies in the side slope protection of the municipal road in the west regions.Combined with the reinforce- ment of side slope and the engineering practice of protection in the municipal road harnessing pro- jects,the article introduces the shotcrete rock bolt support technique from the aspects of scheme se- lection,design,construction and engineering experience.The practice makes clearly that this tech- nique has many advantages of strong adaptability,good economy,short construction period,safety and reliability.It is worth to spread the application in the similar municipal road harnessing projects.
